Mm.

So,

So, uh now.

Hi Christa..

it's the Hi Sammy. It's the detail design meeting, so we're going last meeting. So um, first uh Mark and Rama are going to present uh the prototype. Uh then uh Sammy will propose some uh crite cr criteria to evaluate this prototype. Then, w we.

Yes..

Yes..

And then we going to do some finance to see if uh it is uh feasible

And chocolate?.

and uh at the end we will we will um evaluate ourself as a team. And that's all. Okay. So first, let's uh see the prototype.

Mm.

Yeah.

Uh, here we have our prototype model.

Okay. And you have some slides then?

Mm-hmm.

Yeah. Yeah, we have also some slides.

Yeah. Mm.

Yes, and place some slides.

Okay. Uh so in which uh.

Uh, participant three. Prototype.

In Yeah.

Mm okay. Mm.

Five.

Uh, so this is our remote control.

Him.

It's a r working prototype. You can use it now by switching all these buttons. So first, I present as we came to this perfect model,

and then we'll give some technical specifications.

Yeah.

Mm-hmm.

That's well, so that's that. Please, next slide. We analysed all the fruits

and contacted NASA, and uh made some real good.

MASA?.

Yeah. If you can see this, and the stars are showing that. And um, s society will accept that. For sure.

Mm-hmm.

And making some analysis of different fruits, we choose the ultimate form, ultimate colours, and uh ultimate smell of it. S please, next slide. But we still didn't want to go far from our titanium idea,'cause it's the most of the moder the m the modern material we can p select. And it's practical. And it's still say it's for our needs, so please press something. And as I said, it's perfect..

Okay..

Please press it.

Experience. Explanat

Everyone is f really uh really glad to obtain an s such a r such a device.

Such a nice thing..

See this..

So you can touch it with your hands.

Can I?

Sure. Yes..

You can.

Ho-ho. imitating flatulence].

What do you say?.

N

It says.

You must say it.

Spongy.

I will uh.

One day.

I'll buy it..

Yeah..

If I if I need so..

He.

Hopefully my daughter will like it..

Okay. Y and we got the answer. Uh, it is, yes, of course.

Yes, of course. Of c course..

, please next slide. Um, this is a prototype. You can have a look at it, and That's all I wanted to say.

Ah.

Now it's technical specification by our colleague.

Hmm.

Hmm.

So.

Oh, there is a button missing.

Yeah.

Okay..

This this is really flexible. You can add your buttons.

It's in option..

Yeah. So function, mm.

Mm-hmm.

So, as we discussed, we have to switch on switch off whenever we want. And so, we have buttons and using L_C_D_, or like you can use this jog wheel and select which ever option on the L_C_D_, and then do on and off. Then you ha you'll have volume control. So, you you can press these buttons to increase or decrease the volume.

And we have some L_C_D_ controls. Like, m switching the L_C_D_ display if you want to use L_C_D_, or you don't want you can just use normal button.

Mm-hmm.

And we have speech recognition. Here you have microphone, and then it date records your voice, and then it try to recognise.

Hmm.

And it can also do the action.

And location finder. And we want to do the location basically using speech recogniser. You can just say, where is my remote control.

Mm-hmm.

Or uh, you can just give some nickname to your remote control, like Bobby.

Bobby. Mm-hmm.

Hey, babe.

And then, it will say hi..

Bob. Hey Bob..

Yeah, hi, and then you can use it..

Okay,

Hmm.'Kay..

that's good.

So, um our team is now fruits. Mainly strawberry. So, you can have.

Oh, these are strawberries..

And then you can see the look L_C_D_ and all the switches.

Are colourful. Yeah..

Material, we want to stick to titanium. We will send, we want to.

Fruit smelling spongy titanium. I didn't know it exist, but that's great.

Yeah, or s So, we want to have simple and perfect shapes, like I shown in these phones. You can have your own designs and and you can feel simple designs. And you can choose colours on your day for each day, or even many colours.

Ha.

Ho-ho. That's for the L_C_D_ or for the titanium?

You mean we can change the colour uh of th

For the L_C_D_.

Yeah. Yeah okay, for the L_C_D_.

With titanium it's it is silver.

Tit titanium is.

We are still working on titanium.

Mm-mm.

Yeah.

So, r we'll start with L_C_D_.

Uh, okay.

Mm, yeah..

You can ask Bob. It's Tuesday..

Yeah.

Hey, you know you're theme today..

Yeah, Bob, please. Tuesday colour..

Yeah. Even you can configure your colours for its the depending on your mood, or s

Okay.

Hmm.

Mm-hmm.

Black for Sunday..

And you can have many colours on weekends. Or.

And w wait, wh what are the strawberries for? Wh wh

Huh?

On the L_C_D_?

Ah, these are like sensors.

Oh.

Mm-hmm..

Of course.

That's location sensors.

What do you think? Strawberry sensors. Very useful.

Okay. Strawberries.

So,.

after this meeting we'll propose a party for our success for.

Ah..

Lounge meeting..

So, if you are vegetarian or you have any options, please let us know.

Yeah, and we can just some strawberry first. Um.

Yeah.

Okay. Mm-hmm..

Alright. Good..

Oops.

S

So, huh. Interesting. In interesting. Mm mm.

Uh.

So, any specific questions for.

we'll see in the financial part if uh all gets into.

It makes sense.

Yeah..

Let's make a party first maybe..

W Who is the five uh fifty millions we first make a party in?

Yeah. Then we can discuss We can Yeah, then we can have how much for how money is left..

So uh, this is.

Mm-hmm.

What a design.

Okay. Uh, so Let's uh,

It's my turn.

yeah, let's see if uh th it's meet the evaluation criterium..

Mm-hmm. Let's see if this Yeah, if you meet the evaluation criterion.

Yeah..

Oops.

Fudge.

Yeah. So, evaluation please. So. You made a very nice prototype, and um, I think, we now need altogether to try to evaluate it to see if it makes sense to do it, if it fulfils our what we want to do, and things like that. So mm Uh, next slide, please. As you know, before going and uh creating and producing these strawberry uh remote control, it's very important to first verify if it makes sense, if we have a chance to sell it.

Yeah.

Uh, so we need to evaluate it um, try to do it in a constative way, and as much as we can. To so what I propose is that we are going to to have this scale from one to seven. One meaning that, ye yes uh it fulfils uh the the criterion, whatever it is. And seven meaning, no it doesn't fulfil at all. And we're all l going to list all the criterion. I'm going to go to that next slide,

Okay.

and together try to evaluate this according to this criterion and from one to seven. And then we are just going to have an average, which will give us the value of our uh remote control. So, maybe we can have a look at the criteria?

Fancy.

So these are the criterion uh I'm I thought were important. Of course, this can be discussed, but let's let's see, so let's vote. So we have fancy here and we have the scale from one to seven with four in the middle.

Mm-hmm.

Huh.

So,

Yeah, what's is really.

what do you think, is it fancy?.

Uh, it's really.

Uh, I think that fancy, we can say it is fancy..

It is very very fancy. Or have you ever seen something like that?.

Oh. I am not the d the only one choosing, yeah.

Yeah, of course.

Uh what do you think?

What do you think?

Feel the weight.

Is it The weight is later.

Yeah. Oh.

Really..

Uh-huh..

Now we're.

Okay.

We're on the fanciness now. I think it's quite fancy.

Yeah, yeah.

Yeah. Yeah.

We can give at least five or six, seven.

It's uh Yeah, so No it's it's one.

It's in the other.

Oh, Oh. So Oh, okay. Yeah, okay. Oh, okay. So.

Yeah, o one means it's, yes, a very fancy and seven mean no at all.

Mm..

So it's one or two.

Two. Let's say two, yeah.

M maybe two.

What do you think? Two?

Two. Two.

Okay. So here, two. Up.

Technology.

Then we have uh technology.

Yeah. Um.

So, what about technology? We have uh we have speech recognition, we have location based,

And we have L_C_D_.

we have L_C_D_.

Change colour of t

So you change colours.

Change colour, I mean that's very.

Useful.

Yeah, I think it's a.

Quite

Yeah, yeah, yeah.

d I think it's a one for that, at least.

Yeah. Yeah.

Yeah. Uh.

Yeah, yeah. It's silly.

At least a one, yeah.

Mm-mm..

Robustness, uh-huh.

Uh, still we need to cha.

So let's suppose my daughter take it and um and through it away.

Um.

Do you think it makes sense that it's going to live again? Uh, maybe not the prototype.

The strawberries.

Yeah, it.

Oh..

Let's try. Oh my god..

Maybe strawberry.

Okay, we just lost one strawberry.

No.

Oh.

So.

No. How can I say this.

Not at all?

Yeah, we can easily plug it.

It's still it's still working, and your daughter got a bonus.

It is Yeah. Yeah.

A strawberry.

So it's not so bad.

Mm-mm.

Yeah, yeah.

I um uh I would say three.

Yeah. But it's too.

Yeah.

It's um robust, yeah.

Yeah, that does make sense, yeah?

Useful?

Useful. Well, so the question is does it have uh the minimum requirement of re remote control?

Yeah,.

So I don't know. These buttons are uh It not clear.

Oh, yeah, lets me try.

But you have at least uh next produce.

Yeah.

Yeah.

What is uh next, please?

Yeah, channel. I this is volume control and channel changes. These are the main.

Uh, it depends on the.

And you can uh do di two sites?

Okay.

You.

Yeah.

Yeah. Yeah, and you can do on L_C_D_ using these going to scrolling all the option.

Okay, also.

So if you don't want.

So but, for instance, because the L_C_D_ is not uh touch control, touch screen, you cannot go to channel twenty five directly.

Yeah, um yeah.

You can, by using the.

You can.

Yeah.

Directly.

You go you.

You c push here the the.

So, the basic mode.

yeah..

Yeah. So that's simple. The basic mode is uh you got just two buttons and a jog dial.

Yeah.

With two buttons, you do this like uh volume up, volume down.

Oh, it's a jog dial, okay.

Or if you go to the site, it's channel up channel down.

And channel.

Uh-huh. Okay.

And if you want to make to s twenty-five, you push on this.

Yeah.

You select twenty, you select five.

You can select.

Okay.

That's it.

Yeah mm.

It's much longer than that that being two two five, no?

No.

Don't you think so? May not okay, we can go. That's uh You're right.

Yeah, yeah, yeah. Y you need to like press two and five and Yeah.

That's it's less uh Yeah. But it's it's nice, because people anyway don't go there.

Yeah, yeah. Yeah mm.

But So what do you think for it, usefulness?

So, d Yeah, we need to address we want.

Seems to be useful..

we only address two main functions here and the other functions will be on L_C_D_. So

Let me understand well,

so.

because I'm not sure that's for that this one are b d uh two dir directional button.

Both. Yeah. Yeah.

Yeah. Yeah.

Yeah.

Yeah.

Yeah. Up.

Up down or left right. Yeah.

Yeah. And which what is that?

It's a jog dial for controlling the cursor on the L_C_D_ screen.

This is jog wheel.

That.

Okay, okay. It's a kind Oh, okay okay..

Like, selecting the menus.

Yeah. Um, see in L_C_D_, like you will have blocks and you select which one.

Cool.

Oh oh okay, great.

I would say then uh.

Now it's looks us useful.

Yeah. Yeah.

Two or three?

Yeah.

Two or three?

Two, maybe..

Two.

Yeah.

Okay, two. So size and weight.

Yeah, yeah..

Is it the the the effective size and weight that the Is it uh real size, real weight? Or Because it.

Yeah, it's size al almost.

Size is going to be that, yeah?

Yeah, because it is.

Uh, and and.

The weight will be bit lighter. We will s We use titanium.

Sure,

Mm-mm.

without titanium alloy, it's going to be light.

Yeah. Yeah. Yeah.

It's going to be lighter,

Of course.

because this seems to be very heavy f I mean,

Heavy. Yeah.

for my daughter, for instance.

Mm-hmm..

Yeah.

Not sure if uh she can use it..

But sides uh, the sides should be okay.. Yeah

So, should be okay.

mm.

Up to three for that,

Mm-mm.

because I'm haven't seen the weight so I must not uh.

Okay. Okay.

Oh.

Colour and shape.

Uh-oh..

Well, so colour, it seems that we have the several colours for the L_C_D_.

Yeah.

Yeah.

But um, it's not very clear what is the colour of the sh the sh the case.

Yeah.

The case is silver titanium, no?

It's a it's going to be titanium. Okay, okay.

Yeah, it's.

Yeah.

That's nice.

Let's imagine.

I think it's good. Okay.

And what about the strawberries on the top? I'm not convince. But maybe I'm not trendy. But, uh.

Yahoo. Well y you know, it's this uh fruit and vegetable year.

Oh. Yeah, yeah. Yeah.

Yeah, but uh uh they're not useful.

So.

I I mean it that's uh.

So maybe, I think.

Uh, I think usefulness is m as as I rem um just have to remind you that usefulness is much less important than fanciness.

Mm-hmm.

Yeah.

Yep.

Yeah, well.

Whether it's fancy or not now, it we have to decide.

Hmm.

Yeah. Um.

But this

I would have m uh i found more fancy that the fruits are useful.

If it's Uh-huh. So, that they will that maybe the fruit may be here instead..

Yeah.

Yeah, well then it's bit difficult to use. Not like this d We're just giving the fruit for more fanciness and more attraction, too.

Mm-hmm. But the n Yeah.

So, maybe think we can have rubber or some sponges, stuff for strawberries and different colours.

Mm.

So it's.

So, it seems we are not so clear on the shape uh.

Even.

No, I'm not sure uh why.

These buttons.

uh if it was like this.

But it looks really not really good.

I It's n no, it's not fancy any more.

I mean, the f Yeah. So these are kind of rubber things. Even if you lose one you can just put whatever.

Okay.

And.

Even we can provide many different colours or different fruits, and.

Uh-huh. And different routes. Okay, I see what.

Moreover, moreover it covers it covers all the end goals. Even if it is, you know, it's very rounded,

Yeah.

but still you got some rubber fruit here, and it's completely uh completely secure to leave it uh with children and that.

Yeah.

Okay, so you you you feel like it's something uh a protection for the remote control.

Yeah. Yeah. Yeah. Yeah, we've yeah we have sensors here and so here and here,

Also.

so we just Yeah, so even if you don't put, it works. But this is really fancy..

Okay.

I suggested three.

Okay..

Because uh, everybody s doesn't seem to be convince,

Okay. Okay.

although it's quite.

Yeah.

You have good arguments.

Yeah.

But.

Okay..

And uh the last one is adaptive. This is not r maybe not as important as the other one,.

Yeah.

but uh can we adapt it to each each personal use?

Sure, sure, just look at it. It's full adaptable..

Great.

Wow, that's a.

Fully adaptable.

Yeah, you can fit it into your palm, you know.

That's Yeah. So you can fit into your palm, okay.

Yea

Yeah..

That.

You can.

What else can we need?

Yeah..

You Do you think you are gonna be able to do that with ti titanium as well?

Yeah, it's fudge titanium. You know.

It's fudge, yeah, yeah.

Right, yeah. And uh.

Mm,.

Yeah, fruit titanium, yeah. Well, I if if this is if you are ready to do that, then I think it deserves a one..

Yeah..

Okay. Let's go for one..

Okay.

Yeah.

Now we have to do the average..

Three, three, six, eight, eleven.

Who is good in math?.

It's two point one seven.

Okay. Two point one seven. That's nice. Two point one seven out of seven.

Hmm.

I think we have a good good thing.

Yeah.

Well, that's all I had to say about the evaluation.

So it's a good evaluation.

So It seems to be good, yeah.

Yeah. Mm.

Yeah mm.

We have uh.

Yeah, two one one seven, we have. So.

Yeah.

Mm-mm.

Yeah. Okay. Thanks.

Okay. So now, it has to fulfil the financial criterium?

Financi

Ah-ha.

So, I have an Here. Um.

Energy.

So so how many batteries do we need?

Uh, we use bat One battery.

One battery?

Okay,

Yep.

so two.

Good. Why two?

Oh, we just need one, I guess.

Say no. No, ne never install.

Uh-huh..

Two batteries or one?

Oh.

No, number is one. We need only one battery.

Yeah yeah,

Only one.

but the price is two. Oh, number.

No, no. But no, no. No, no way.

Sorry sorry sorry. I'm sorry.

No, uh you just.

Number, number.

Number. Yeah.

Yeah. Yeah. Oh.

Yeah. You never use uh Excel?.

No, never..

How.

Good..

What what's the limit?.

H.

It's twelve bucks.

Uh, it's it's okay that I don't know,'cause uh it's not my field. Twelve bucks. Okay,

Twelve bucks.

now Mm-hmm.

Twelve and a half, I think.

Check that number also..

So we.

Okay. Okay, electronics.

We have sample chip.

So.

Uh, like simple chip, yeah.

It's a simple chip?

So, yeah.

Simple chip, okay. One.

Yeah. Four buttons at least.

Okay.

Okay..

And then we have the t sample speaker sensor for speech recognition..

And for the One also.

Yeah, one to one.

One or two? One?

Yeah, one.

Okay. So the case, which one uh is it in the end?

Yeah, I think we will go for a single curve, no?

Let's do a single curve.

Oh, is.

It's it's flat.

Oh. Oh, okay.

It's flat, and curved.

I thought you can curve

It's flat.

somebody..

But it is flat,

It's curvable..

you Look. It's curvable, but it's not curved..

Maybe there is a supplement for that, no?

Mm-hmm.

It's only curve?

Oh see, I I think that the the price is this one.

Okay, let's go.

Yeah..

This Okay,

Yeah, yeah.

you d.

Don't chip on me.

We tried, we tried.

Oh, okay.

Oh. Titanium.

So, what is it? T titanium?

Mm-hmm.

Mm.

Mm, that's expensive.

Mm-mm.

Mm-hmm.

Mm.

Yeah. But she wanted u the fudge titanium.

Okay..

Yeah, well.

Let's stick to s titan.

I think it's five, but you don't say..

Special colour?

Well, n Why three?

No, only one, no?

No because uh.

Mm.

Why three?

Oh, sorry. Again, I'm See it.

Um.

Yeah..

Special colour,

Interface.

or it's only on the.

Oh.

Yes, in L_C_D_ display.

Yeah, but there is no colour here.

Ok Yeah, an Yeah.

So I put it here.

Push-button.

So the L_C_D_.

How many push-button?

Scro

Three or two?

Uh, two.

Two.

Is there The scroll-wheel, okay.

Yeah.

Yeah..

One scroll wheel.

It's going to be expensive..

One L_C_D_ displayed.

Okay. Um That's that's not.

That's all?

We choose this one, and not this one.

Yeah.

No. Oh, I think, no it's.

Yeah, it's cheaper.

Uh, is it a scroll wheel and pe push button, th this centre one?

Or only a scroll-wheel.

Yeah. Only scroll wheel.

Or only only scroll wheel, okay.

Yeah mm. So.

You try to s.

You are trying to make make up make us up.

No, no, no.

It's already.

Because how do you do to y select?

Ah.

No, but you select with the two d the other two buttons,

Yeah, I mean you you go on the location with your scroll wheel

Y ye

no? That's true.

and then you.

Yeah.

Yeah.

Then it automatically we can just do like you feel, it goes. And it will activate.

Yeah.

Stay longer. Okay.

It should stay. Yeah.

Oops..

Um, plus, yeah, it's price is really.

Okay, okay. Um.

Special colours, yeah.

Mm-hmm.

For buttons.

Okay.

No,

Yeah, buttons and strawberries.

buttons just normal.

Yeah. Special form.

You you have all of these, no?

She's very hard on this..

Mm maybe n not this one but.

Special colour? Yeah. No. Special material?

That's for buttons.

Uh, we have titan

But buttons are standard.

Yeah, buttons are the standard buttons. Yeah. It's only buttons, these.

Yeah, so.

Nothing special.

Yeah.

Okay. So we are at seventeen dot eight.

Not special colours an interest in?

No, the colour is in the L_C_D_.

And buttons are not colourised? They are m

Mm, hmm,

I no.

I think uh because you can just go for a good colours.

We can just use this red.

Yeah, and uh.

It's.

Boo-hoo. It's already too expensive. Apparently.

Yeah.

So what is Are we supposed to cut things out now?

Yeah. Mm.

Uh, until we get twelve fifty.

Mm-hmm. Mm..

Oh..

So think of what we can cut uh here..

Well, if I look at what is the most expensive things, uh it's the L_C_D_

Sample speaker.

and the speaker.

Yeah.

Apparently, we have to choose one or the other..

Yeah.

Yeah. Yeah.

Well, as you may know there's some research done in the field of producing energy from mechanical eng, I mean, producing electricity from mechanical energy. So, the point is that when you take device and push the button, you produce enough energy

But you don't need a battery?

to make electricity. Yeah, that you don't need a battery. So, it's something like hand dynamo robot. A real high-tech version of it.

Mm-hmm.

But um

So that would.

it's like the hand dynamo, no?

Maybe the jog wheel can be like kind of hand

So, but if we select the hand dynamo it's okay, we only.

is.

We we win one.

Okay,

Yeah.

That's already that.

Uh it's a it's a beginning.

Okay, let's do that.

Okay.

Why not.

Yeah.

Let's do that.

So One here and here.

Yeah, just remo

'Kay.

And I propose to.

S

So uh, about chips. Advanced chip on print, right?

Mm-hmm.

So, put minus one there, please..

Mm.

I'm not sure if this is legal.

Yeah.

That's right..

Why not?

Uh, no.

And?

And?

M maybe minus uh three, no?.

Yeah.

No..

So, was there result?

No, no. It's not.

Okay, let's see.

Mm-hmm. Mm.

Let's have a look.

It's not changing, no?

Why?

It you don't

Yeah, yeah, yeah, if Click somewhere, you'll see features.

Oops.

Yes, it does.

So.

Maybe put minus two, so it looks uh more reasonable..

Yeah. Why not.

Yeah, anyway.

Oh, sorry.

Minus.

No, minus two.

Mm-hmm.

Nobody will know.

Mm..

It's not recorded, is it?

Good.

Okay, we're on time.

Okay..

Good.

So now on, we can increase our Still you have two more..

Oh, we can put uh a hand dynamo and a battery if you want.

Maybe we can use it for our party.

Oh.

And a battery and a battery, yeah.

Yeah.

Both its it's cool..

Yeah, yeah.

No, now we are exp exceeding I think.

Now it's fancy,

Mm.

let's add one instead of two..

Yeah, that.

It Is it?.

Yeah, yeah y

I think we're exceeding now.

No, but point five point three.

We have to remove the.

Okay.

Uh, it's better. I think they are counting uh.

Yeah. Mm. It's maximum

Is really strict?

We would prefer,

and don't have to Yeah, yeah.

Oh.

yeah. Maximum is maximum.

Uh.

Oh yeah.

So, remove one of them. Yeah. Okay. Okay, we're uh on target.

Uh, mm-mm. Yeah. Mm. Okay. Mm. So target reached..

I'm just curious to see this

Ho.

uh my address chip on print.

It's um English uh Yeah..

Trick. Uh, I would say it's the Russian trick, but

Yeah, but uh is uh English. So.

Anyway No,

Oh. Uh.

Mm..

Well, I don't know.

they may have some their origins, strange origins.

I don't know. I am not sure who was programming this calculator, you know.'Cause uh I wonder if we put A_ or B_ somewhere instead of a number.

Mm, let's try.

No, no, no.

And we can discuss all these things in our party.

Let's finish this meeting instead..

Okay. I save it uh.

What else?

Okay, so next mm.

No.

No, that's yours.

This is right.

Sorry.

Okay,

'Kay.

so finance, that's done. Are the cost under twelve?

Mm yeah, very much.

Yes. Project evaluation, good..

Okay. So now.

Next slide.

Project process.

We have to make um.

Safe uh asse uh safe assessment.

Yeah. Yeah. Mm. See mm how Are we a good team? Mm..

Okay.

Yeah, I think we've listened to everybody.

Mm-hmm.

Everybody could say what they thought.

Mm.

And uh.

Is there enough room for creativity?

Yeah, yeah.

Yeah, yeah.

Mm. And you..

Yeah.

Yeah. When we see the results, there is no doubt there.

Yeah, it's really.

Mm. Oh. Okay. Well, project evaluation.

Maybe a lack of leadership?.

Yeah.

M maybe not, huh?

Team-work, very strong, I would say.

Yeah, our team-work is really strong.

Team-work, no problem. Means. Whiteboard, digital pens.

Oh, we still, I guess.

What was the Oh yeah, what was good? Everything. What was bad?

Yeah, I think white-board is useful. Digital pens, useful.

Hmm.

New ideas found?

So, you say, is there sheep?.

Yeah.

Luck. Okay. So luck, but good..

But uh.

Which imply good uh team performance.

Yeah,

Yeah. A good leader, you know, a good leader is somewhere in the shade and.

but uh then I I mus That's true. And there's uh one very important point.

Don't really.

We're on time.

Mm-hmm.

Yeah. And we also.

Meetings finish when they have to or even before.

Mm. We made Mm..

The for meeting it's uh one of the most important thing.

Of course. Uh.

Okay. Mm..

Not to waste time, that's important.

Yeah. Yeah, we have other uh remote controls to create..

We need time f

Hmm.

Okay..

Ah, we got new idea, speech recognition, location finding. New materials, new s uh this fancy strawberry design.

A lot of uh.

New materials.

Mm..

Yeah, uh new ways of doing financial.

Mm, yeah. Hey,

And new tricks..

just wondering if my uh what about the the pink the pinkness of that uh

Mm. Mm. They're working on um pink titanium..

. They are working on a.

Ah, very.

Okay, good.

Budget.

I think we are great.

Yeah.

There's no no other words for that. We are probably the best.

Alright.

Mm yeah. Yeah,

Real Reaction is uh

we're really nice.

Yeah. Yeah.

Yeah. Mm. Okay.

Finished?

I think it's.

Ah, celebration. Are the costs within the budget?

Yeah. Uh.

Of course they are. Yeah.

Yeah.

How.

Okay.

Is the project evaluated?

Yeah.

Yeah, it is.

Yeah, yeah,

Yes, it is..

it's.

Mm..

We got two.

So, we see, we can even forecast. they propose us like celebration, everything,

Good score.

we could forecast it, right?

To whom? To the whole our company?

I'm the one, proposing the celebration.

Oh, okay..

Of course,

You? It was you.

you know I'm the program manager..

Okay.

So, let's celebrate. Uh.

Mm-hmm.

So where we will go now?

Ah um,

Uh, ye

I think it's finish.

I think the meeting.

Will go to Italian restaurant, or.

The meeting is over at least.

Yeah. Mm.

Ah, okay.

So, we have to go out..

We can decide.

Mm-mm.

Okay.

Yeah.

And we go to the party..

Yeah.

Yeah, yeah, yeah.

Thank you.

thank you to you. Mm.

Okay, so now we are on the conceptual design meeting. Uh y getting close to the last

Mm-hmm.

is the penultim meeting..

How was lunch?.

Mm great..

Thanks.

Don't be sarcastic. Mark..

So um I will again do the secretary part uh we will have three presentation first um uh the industrial design, first Rama then Mark and then Sammy.

Uh Rama.

Ramaro.

Um um we have to take a decision on the control remote control concepts and we have forty minutes.

Mm.

So what we want to the decision we want to take on this meeting are on the um first on the component concept, so what kind of energy we use uh what kind of chip on print and one ki kind of case. And also on user interface concept uh what kind of interface we use and if there is some supplements. And at the end um Sammy will give um a trend watching on what he's he's been doing. It's So, let's go. First with Rama. Participant two.

Yeah, participant two. Component.

Mm-hmm..

Yep. So we're to mainly design f mainly need to know which components we'll use for energy, and the material and interface. For energy there are maybe two or three possibilities. First one, we can use simple battery, or we can use traditional solar cells or mm and the material we can have plastic, rubber which is good for this R_S_A_

Ah.

and then uh titanium, which can be which have very good look an and then interface we're to use push buttons or liquid crystal d L_C_D_ display. And we can use some, moving kind of thing. So, as we discussed before, we need to we would like to have some speech recognition s chip in our remote control. So this can be simple kind of programmable chip and which can use microphone sensors. And we also want to look at our remote control, so. Still we are looking for possible uh technical uh specifications and how w easy we can do and within our pri range, like we're to in our twelve Euros or around that. So we are looking for simple devices or simple technology to do the location of remote control in a room or in a house.

Mm-hmm, okay.

So uh we discussed an Excuse me. So we would like to propose battery instead of solar cells and it would be problematic uh to have enough energy with the solar cells

Mm-hmm.

and so we would like to just use simple battery. And also we want to go for titanium design instead of rubber or and well the problem is with this design we found that we can't use double-curved shapes.

What is a double-curved shape?

Like you can have two curves.

Uh-huh.

Why?

Uh it's I think in manufacturing I guess it's problematic. So, we want to go for simple push buttons because it need a simple chip and it's really lesser uh re really less expensive compared to L_C_D_

which are uh which needs advanced chip technology and it's more expensive,

Mm-hmm.

since we want to put some other features such as speech recognition

we want to reduce uh cost.

Um I want to know why it b uh just uh sorry but for the point before uh why not the rubber, if it is something that it seems to be light.

The cost.

Uh Uh And also like in if you put a it's be difficult to do all the moulding of buttons and these things

Okay. You m titanium it's more uh.

and Yeah.

W we can use something like you know the whole body's titanium but there are some rubber or I dunno some rubber parts like

Yeah.

Mm like this?

Yes so mm.

to make it feel better and to you know.

Like in cell phones recently

Uh-huh.

Yeah. Yeah.

these you can with the rubber in four directions and.

Mm-hmm.

Okay..

yeah. But full assembly We'll use mainly for titanium.

Okay.

rubber is expensive

Okay.

and also it's bit difficult to do all the shapes uh.

Okay.

And this push buttons

Uh yeah so

we we would like to use push buttons instead of L_C_D_s and so we want to mo I mean we're we want to put speech recognition so we want to reduce price on this technology and so that we can have enough space or enough money

Okay, s so simple button and uh speech recognition for the more complicated.

for S S

Speech.

Y yeah we have simple buttons and speech recognition technology,

Mm-hmm.

Okay.

Okay, and still we have.

so.

mm can we still include the L_ L_S_D_ display?

L_C_D_ yeah L_C_D_.

Uh l

Seems not, it's either L_C_D_ or push-button.

So uh

No,

it's like a.

it's not gonna be a t no touchable but still like a source of information or source for menus.

Ah.

Yeah maybe maybe we can see depending on how we'll come up with our full design then if we have enough money or like for and.

Okay, so let's try it, let's t

because the speech recognition technology will take at least five Euros or or something so we want to reduce the cost on display

The L_C_D_ would.

or this inter

The display would only be display and not uh touch sensitive you mean.

Yeah, yeah, it's it's not gonna be a touch pad, uh just a display for giving you information.

Just uh for output, yeah.

Ok Yeah, that can we we can consider,

Yeah.

Mm-hmm.

because like it won't take much money I guess,

Mm-hmm.

because.

Okay.

Okay, yep.

Mm.

You have any further questions or?

I guess no um. So the batteries uh are going to be very light.

Yeah. Yeah, we're to go for li and now I think we have many options in the market so we can go for small nickel or alkaline batteries

Okay.

Mm-hmm. Mm-hmm.

for really light batteries and with uh good price.

So this device on n that can be used for speech recognition could also be used for just uh the finding it basically, instead of clapping why not just be ask.

Yeah, that's then the the one thing we want to know is like because remote control is used for like in the household so it it it will be it m maybe at least five, six people want to use it so so how to uh uh how to define our re speech recognition

Mm-hmm.

whether we want to do s speaker independent or speaker dependent. If we're going for more speaker independent then it would be like again cumbersome and we need really m more technology

Okay,

and so.

for the location. Hmm.

Yeah, if if everybody in the house n to locate then we're to go for some speaker independent technology or something.

Okay..

Okay. So let's now go to the you don't have more question?

No, it's okay.

Um mm thank you mm.

No more questions.

Yep. Thank you.

Puts less of constraint on what we can do

Yeah.

Mm yeah, yeah.

but

Yeah.

it's always like that. We have dreams and the in the end we find out that it's not feasible..

Yeah, but mm.

Oh. We have uh some limitations..

Anyway. Yeah.

But still uh L_S_D_'s already quite nice,

Okay..

L_S_D_ is something else,

and it's quite nice as well..

I'm an artist, sorry..

So,

Um yeah.

So uh, that's not.

go on uh artist..

I hope that's not too much.

Now let's talk about uh interface.

Okay. Uh participant number three.

Three.

Three.

Uh

Which one?.

Hmm..

mm mm uh have a look at this.

no it's yeah.

Okay.

Uh so the concept of the interface. Generally I developed quite a broad concept not only for the interface, but for possible instruction or user's manual and uh all the complex things that come together with your T_V_ and remote controls. So let's start with this. We got our perfect remote control with a lot of buttons

and uh we got explanation for every button

and you can use your time and uh it will take i some days to learn all this buttons and um the L_C_D_ is going to be somewhere here and uh go back button, I don't know really where it is, maybe one of this buttons, and um power on and off mm I I don't remember

Mm.

so uh it it it should be maybe this button is power on and off? Or no? I can see nothing. So that's our concept. It's called the millennium remote control.

Let's change millenniums..

So

Yeah.

maybe you can use in the end and.

doesn't make sense. This is very ugly.

Really?.

I thought you like it. Ah okay

Oh no,

just press the button, please uh..

too much concept.

No.

Ah.

Uh.

Yeah, we will not use this. We will not use this.

But instead of this I will devise That's our concept.

Ah, back today..

And it's got just few buttons, quite low looking, and all this stuff we already we already discussed.

Mm-hmm.'Kay.

And uh what will people say? They'll say it's perfect. Or what will say? Uh they will say it's splendid. And uh e everyone will say I'll buy it.

Mm-hmm.

Do you think it can come in several colours?

And everyone's gonna be satisfied.

Or did the.

I would make a backlight of the L_C_D_ screen with different colours.

Um but not the case.

Not the case.

Uh the case would only be in that uh aluminium uh titanium stuff,

Yeah.

like.

Mm.

Because apparently from your survey people like colours, no?

Yeah.

Yeah, well they like uh something which is uh.

Okay, so let's remember there's a Nokia phone which changeable panels.

Mm yeah, okay,

Do you like it?

so that would be the option. I don't know I don't have a Nokia phone,

But it's uh.

but I don't use that but again, uh I might.

That's why you don't have it. That's why,

Yeah,

'cause it's nasty..

bu but.

But it would be expensive, no? If you use colour L_C_D_.

No.

Uh instead of that maybe we can change the colour of the assembler.

Mm-hmm.

Maybe we can just if users want more colours they can pay more money to get this uh the shapes and they can have different assembly.

Um, I am here.

Okay.

So users have different I mean they have their own interests, colour interests and so.

So?

Mm-hmm.

So we can just if they want they can just pay another two Euro.

Uh-huh, okay, so

'Kay.

you you propose something with option i that increase the price if we if you want o more colours on L_C_D_,

Yeah. Yeah yeah yes. If they want like uh so that we can yeah.

Kind of upgradable uh remote control.

yeah.

Yeah.

Okay.

Wow, wow.

Just they'll get few more things and few more colours.

Okay, what uh there's one more decisi uh one more solution in fact, um'cause there are some some paints that can change colour according to where they are, like they can reflect different colours depending on what is around, like what colour is around, and depending on the temperature,

Lights, yeah.

Mm.

And thermodynamic also. Mm-hmm.

Yeah.

Like a chameleon.

Mm-hmm.

yeah.

Yeah yeah.

We can make it in fact.

Yeah but that's maybe mo too much expensive, yeah.

If if if the.

Mm.

okay.

Mm-hmm.

But uh it can be in uh maybe in an a gradable version,

Mm-hmm, mm-hmm,

but.

Yeah.

so.

Because uh I think there are two kinds of people. Those for which the remote control is uh is to be uh something useful uh I'm going to talk about this later but and those for which is something that that that uh is uh specific to them so it it's like a signature. My remote control is pink. Nobody else than me has a pink remote control.

Mm-hmm.

Uh-huh.

And that makes me special.

Okay

and you think that we don't have to make to make them pay more because of uh o or this is.

I think I think they would be ready p ready to pay more for that.

Okay, so

Those who wanted to have it pink.

so i it's not uh a s base service

Uh.

No mm no.

it's a.

So,

Mm.

be an option,

Mm.

yeah.

It might be optional, yeah.

Okay.

But those people will be really few, no? So like we can those.

The the young people the young people want to be different from their friends.

Ah.

Although similar but have something just slightly better. Pink.

Mm-hmm.

Yeah.

So m so

Mm..

maybe that's if that it's a selling point maybe it has to be the base.

Yeah, yeah,

Mm. Yeah.

yeah. But you know if you want to be different you just take your remote control with you all the time.

And you'll be different.

And it makes you different,

Yeah, yeah.

you know?

You always have your remote.

Uh in the train uh, hello uh no. Want to change my neighbour.

Anyone has their remote controls here?

Oh, you don't? Yeah. You don't have your remo.

No?.

Wh you you know like for instance take the iPod. It's a kind of remote control. Uh it's white

Mm-hmm.

and it's so white that you see it from any anywhere.

Mm.

It has this distinctive look and feel and look which people seems to like.

Okay.

just because it's a colour that we don't usually see in a remote control. White.

Mm-hmm.

Uh-huh, uh-huh. Could we integrate something into our remote control, something like light?

Seems important.

Hmm.

That they can use it in darkness, like. Hand light,

Mm glow in the dark,

yeah.

Yeah

so.

maybe like the infrared like we can put some radium chips or something

Mm-hmm.

so that like at least um.

Iradium?.

yeah.

Okay. Okay.

Yeah,

Ah sorry. Mm.

that.

Okay. So mm.

Okay. S well,

Okay.

let's go on maybe with the presentation.

Yeah. Uh-huh, yeah sure..

Mm-hmm..

And um the remote control's going to be smart

Oh.

but how smart should it be to not to complicate things too much?

And uh

I dunno

that's a question to you and to mm to.

Well so I heard that uh it seems that speech recognition is something that can be done uh so that's the smartness of the thing.

Mm-hmm.

Currently we don't have guns with speech recognition or uh beer cans with speech recognition

but we may have remote controls with speech recognition.

Okay, okay.

I dunno..

Mm, that's a nice world..

So just just just just think about it um.

Thank you.

Don't touch the remote.

Okay.

But yeah. Are are you saying here that uh the remote controls should be aware of who is using it? So for instance the young guy would not be able to use it because his father doesn't want.

Uh yeah I just want to say it should be real smart.

Like with some Maybe fingerprint recognition or.

Voice recognition is quite tough. I say don't use it, and the control just looks.

Yeah.

Mm.

'Cause I ordered jus To l to l lock it.

Um Mm.

Uh that mm that could be feasible I guess, like So since we have we want to do some speaker dependent speech recognition uh so we can use.

Okay. So it could be smart in that way.

yeah. Yeah, yeah..

Mm. Okay.

But for instance th I I'm thinking about the other uh uh particularity that the the remote control could have. S since it it knows who is using it, it might also record the kind of uh channels you are u more often using and uh levels of volumes that you're more often uh things like that

Yeah.

Mm.

Yeah, sure.

Yeah.

and provide you ways of using them, I dunno, somehow,

Yeah.

I dunno, that might be expensive

Mm-hmm.

but

Uh it's.

that might also be a good sales pitch again.

Hmm.

The remote that knows you..

Mm-hmm..

Okay.

Okay, thanks.

So it's.

My turn?

yeah, Marketing Expert.

Okay, it's alright.

Participant two?

Four.

Four,

Four, I think.

sorry.

Trend, yeah. No uh yes. Okay, so I'm going to talk about trends and um I hope this can help us to to understand l how we should design our remote control. So, next slide please. So first maybe just a small recap on how how do we watch trends so it's not so uh simple you might think that it's easy but uh it's not so simple. Anyway these days uh the best uh source of information is the web as you know, so have to to go often on the web and look at uh what the others are doing, and ask real people who are using real remote controls every day uh or any other tool that is similar to a remote control which basically is a small device that people have with them, always, like a phone. We can we can use the phone as a as a good uh uh example of where to in be inspired. Of course those tha d who are watching the trends are also have also to be inspired because in fact they're not only watching the trends, they're inventing it, they're creating the trend. I hope I'm going to try to help you on that. This is more risky because you're not following the trend,

you try to invent it, which means either you succeed and you make a lot of money or you don't and you're out of business..

So anyway uh next slide please. Uh to be to be quick there's a lot of words here but uh basically there are uh in in the market of of remote controls there are three aspects that we should very pay much attention to. The first one, which seems to be the most important one, is that it has to be fancy, it has to have a fancy look and feel. And uh interestingly this is the very most important thing. It has to be fancy. Strangely enough it's more important to be fancy than to be wi and now that's the second thing it has to be, it has to be technologically i innovative,

it has to be new with some of uh new uh technology inside and uh and this is also uh more important than the last thing which we w may think that would have been the most important, which is that it should be easy to use and it should be easy to use as a remote control. So as you see uh it first have to be very nice, s something that people are proud of uh uh that i uh they can be id identified with uh and and then uh something that um contains very novel stuff that they can talk about with their friends, huh, mine has this and not yours. And finally of course it has to be useful as a remote control but it seems that it's not so important that it's useful as a remote control..

Next slide please.

Mm.

Uh and now in a more uh general uh uh broad way of seeing th uh the thing. If we look back and not uh look at only remote controls I think it's important to see that the trends are quite the same in many areas so currently the the trends that we see in l in l big cities like Paris and Milan, well, it seems that this year things should have uh a fruit and vegetable uh way of of look or feel

or so..

And I think of course uh i it applies to everything. That's the thing with trends. It it can travel f from clothe to furniture same idea.

Fruit and vegetable. Think fruit and vegetable. And uh if we co we compare to last year, now it has to be spongy,

Mm.

What is spongy?

yeah. Well

Yeah

this so so I think uh uh i

kind of um maybe.

When we were talking about rubber,

Yeah it.

I think uh the rubber aspect might be important because it's what is probably more feasible in terms of sponginess.

Mm-hmm.

Yeah.

S So maybe titanium it's not a good idea.

Yeah. We need to think about mm mm.

Seems not, seems not.

Mm-hmm.

Yeah.

Um sorry Mark.

So.

It seems to be.

Think more of uh something in the colours of uh like fruit and vegetables and spongy,

Fruit. Even shape?

as a even in the shape it has to be more round and uh more uh uh look natural somehow. I mean.

More.

Mm-mm.

yeah. Yeah.

And not those futuristic uh remote control with angles and uh and titanium like.

Mm-hmm.

Mm.

Hmm. You're old-fashioned.

So that's what people seem to yeah i I know it's quite far from what you thought

Sorry..

but that's that's fashion and.

Okay.

Okay.

Okay that's all I have to say.

Mm you have questions?

So these abilities are mainly ad addressed by young people? Or it's.

These I'm sorry.

This you you so did you.

Yeah, yeah we have people uh uh listening to the trends everywhere in the world, of course,

Where? Oh. Oh, okay, mm-hmm.

as you know our company is quite big and uh so I'm just asking them what are the current trends according to them when they go in the stores and when they ask uh their uh friends

It's not from mm. Mm-hmm. Yeah. Yeah.

that are also.

It's more general trend

well.

it's not particular to the remote control.

No, it's not it's not this this is very general, yeah. But it seems that trends travel across things.

Mm. Yeah.

The what we.

Yeah but some materials n they're to be uh they're to be something like solid like they can't be really spongy

Sure.

or.

Yeah.

yeah yeah.

We have to I think we have to have the look of fruit and vegetables

yeah, yeah sponge, yeah yeah at least that's.

but we still have to put our chips inside, so of course.

Yeah yeah

This is your problem.

that yeah yeah..

This is not mine..

Yeah. Yeah, looking yeah fruit. These things can be easily incorporated. We can have t colours or this shape

Yeah, I think in the colours and in the uh the kind of material.

or at least.

If if it's something like rubber made or I think it it's also going to be good.

Yeah.

Mm.

Mm.

Mm-hmm.

Okay?

Okay.

Yeah.

No more question? Okay.

Yep. Thanks.

So Mm-hmm. Okay, so we will have uh next meeting in thirty minutes again. Um now you have to go straight on this individual action which i which are for Rama uh wil design,

Look and feel de

um Mark the user interface design, and uh Sammy uh the product evaluation. Uh you will work together uh on a new on on a prototype using modelling clay.

Mm-hmm.

Hmm. Hmm. Mm sounds interesting..

Mm-hmm um and I as always your personal coach will send you specific instruction.

Okay.

Okay.

Thanks..

So, can we highlight the specific features of our.

Yeah you're right, you have to.

yeah, so so we want the speech recogniser and we want some kind of buttons and we want some themes like fruits or vegetables,

So

that's.

you say s

we want to follow general trend.

Spongy.

S

Yeah.

do we agree on that? Yeah. We have to.

So, do you think.

No, we don't have to,

So we have to uh for.

No..

but seems it's the trend.

Hmm. Yeah.

Again, as I said we can also try to make it, to create the trend.

yeah so are we confident enough on creating trends?

Yeah.

So there's no Well, that's you t can try to convince us.

Well, we can make it smell like fruit..

Okay. that's a good idea,

Okay, that's a good idea.

That's.

So titanium smell like fruit.

I.

Yeah..

Mm-hmm.

So what about location and these things, people are really interesting on those features? Or they really like They more want these fancy features

Uh I think i

like.

yeah i it's again in this uh what I said first it has to be fancy so I think if nobody else pro provides currently a remote control with that kind of stuff and if we can provide it I think it's a good sell for us

Mm-hmm.

Feature Yeah.

because we have it

Yeah.

and others don't.

Okay.

It's fancy. Whether it's useful or not doesn't seem to be very important..

I I agree with uh this uh.

Yeah. Yeah.

Now we have to decide on what kind of fanciness. Do we take titanium smelling like fruit, or do we make spongy uh fruity-like

Yeah. Uh we will try to explore these two options

Mm. Yeah, yeah.

and.

Maybe you could explore the two option.

yeah yeah.

Mm-hmm, mm-hmm. Could we make a titanium shape? I mean fruit-shaped.

Uh yeah at least like we can make banana or.

Don't you say that you cannot do double shape uh curved shape.

But Doub double-curved.

yeah it's it's

Mm. Seems to be.

yeah.

yeah that's a we're to look for.

Mm-hmm. Okay.

and and s we're to see the whether rubber is expensive

Okay, okay. In fact I just agreed to make uh to make the like titanium panels on a whole rubber body.

and d Hmm.

Mm-mm. Okay, so

Well, okay w we'll see.

you explore now that you're going to work together these these two.

Yeah

Mm.

Or or spongy an yeah..

Yeah. Maybe we can have two different assembly also like one spongy and one kind of titanium.

Mm.

we have only the plastic or the the chippy yeah fibre chips or.

We'll see. We'll see.

If you have time.

Mm. Yeah I don't think w I think we have to choose. If we choose uh titanium or if we choose spongy

Uh.

but uh it cannot be both.

We'll see. I I really don't like this modelling clay'cause you know it makes some for for

Yeah.

For creation.

I dunno uh yeah um

Yeah.

we'll look.

Yeah.

Ah you can pretend that it's uh titanium..

Even design..

You can paint it afterward.

Okay, okay.

No problem. We have a very large department of paint.

Yeah, do don't worry, you you you speak with mm mm.

You will do it..

Alright, alright.

Okay. So explore a shape.

So still we want to keep L_C_D_? Or.

Mm I think it's what we say, that we have an uh an L_C_D_ with uh information.

Yeah.

Not uh.

Okay.

The thing is that uh if we want to have as he says if we want to have uh a small number of buttons we need to have a kind of output that says currently what their actions are.

Yeah, then we can.

Mm-hmm.

yeah, yeah, that user friendly

Mm.

or.

Yeah.

Mm.

That's the converse to having zillions of button

Yeah.

where each button does only one thing.

Mm.

Yeah.

Okay.

and we just stick with two batteries so it's not any solar or.

Yeah.

Yeah, yeah, yeah.

yeah yeah j yeah,

Classical, we stay classical in that we don't reinvent uh the wheel.

because Yeah.

Mm..

Anyway it's very in general I think people uh change T_V_ more often than batteries of their remote control.

Yeah.

So. Because the trend goes faster than the life of the.

Mm-hmm.

Mm-hmm.

So it's very.

Okay. So

Okay.

are we.

Yeah.

Yeah.

mm.

Yeah, we're done.

We're done.

Okay. So see you in thirty minutes.

Yep.

Question: What did the Industrial Designer propose as a substitute for rubber when making the case for the remote?

Response: The industrial designer proposed using Titanium as a substitute for rubber, as it has a better appearance and is more durable. They also mentioned that they may consider using a combination of titanium and rubber depending on costs and design limitations.

Question: What material did the Marketing Expert suggest for the remote's case?

Response: The marketing expert suggested using a titanium case for the remote, as it was in line with the current trend of using fruit and vegetable-like shapes and materials in product design. They also mentioned that the titanium case could be painted to achieve different colors and textures.

Question: What was the advantage of using titanium for the remote's case?

Response:
* Titanium was considered advantageous for the remote's case due to its better appearance and durability compared to rubber.
* It was also seen as being in line with the current trend of using fruit and vegetable-like shapes and materials in product design.

Question: What were the drawbacks of using titanium for the remote's case, as mentioned by the Industrial Designer?

Response:
* The industrial designer expressed concerns about the cost and difficulty of manufacturing a double-curved titanium case.
* They also mentioned that molding buttons and other features into a titanium case would be challenging.

Question: Were there any other potential materials or material combinations mentioned for the remote's case besides titanium and rubber?

Response:
* The industrial designer mentioned that they could use a combination of titanium and rubber for the remote's case, depending on costs and design limitations.
* They also briefly mentioned plastic and fiber chips, but these were not discussed in detail.

Question: What was the final decision regarding how the remote's case material will impact the color options for the remote?

Response: The meeting did not reach a final decision on how the remote's case material will impact the color options for the remote. The discussion was focused on selecting the most suitable material for the case.

Question: Why did the Marketing Expert believe that the remote control should have a titanium case?

Response: The Marketing Expert believed that the remote control should have a titanium case because it would be in line with the current trend of using fruit and vegetable-like shapes and materials in product design. They also mentioned that the titanium case could be painted to achieve different colors and textures.

Question: What was decided regarding the remote control's power source?

Response: The participants decided to use simple batteries as the power source for the remote control. They considered solar cells, but concluded that it would be difficult to obtain enough energy with solar cells.

Question: What did the Marketing Expert recommend to do regarding the appearance of the remote control, in the context of current trends?

Response: The Marketing Expert recommended that the remote control should have a fruit and vegetable-like appearance, with spongy material and rounded shapes. They also suggested using colors inspired by fruits and vegetables.

Question: What was decided regarding the display screen of the remote control?

Response: In the meeting, it was decided that the remote control should have an L_C_D_ display for providing information, but it should not be touch-sensitive. The participants considered having an L_C_D_ display with more advanced features, but they ultimately decided against it in order to reduce costs.


Am I on? I guess so. Radio two. Hmm. Radio two.

Hello?

Wow.

Mm - hmm. Hi?

Blow into it, it works really well.

Channel B.

People say the strangest things when their microphones are on.

Channel four. Test.

Uh - oh.

OK.

Radio four.

Hello?

So everybody everybody's on?

Today's

Yeah. So y you guys had a a meeting with uh with Hynek which I unfortunately had to miss. Um and uh somebody

Mmm.

eh e and uh I guess Chuck you weren't there either, so the uh

I was there.

Oh you were there?

With Hynek?

Yeah.

Yeah.

So everybody knows what happened except me. OK. Maybe somebody should tell me.

Oh yeah. Alright. Well. Uh first we discussed about some of the points that I was addressing in the mail I sent last week.

Uh - huh.

So. Yeah. About the um, well the downsampling problem.

Yeah.

Uh and about the f the length of the filters and Yeah.

What was the w what was the downsampling problem again?

So we had.

I forget.

So the fact that there there is no uh low - pass filtering before the downsampling. Well.

Uh - huh.

There is because there is LDA filtering but that's perhaps not uh the best w m

Depends what it's frequency characteristic is, yeah.

Well. Mm - hmm.

So you could do a you could do a stricter one.

System on

Maybe. Yeah.

Yeah. So we discussed about this, about the um.

Was there any conclusion about that?

Uh " try it ". Yeah.

I see.

I guess.

Yeah. So again this is th this is the downsampling uh of the uh the feature vector stream

Uh.

and um Yeah I guess the the uh LDA filters they were doing do have um uh let's see, so the the the feature vectors are calculated every ten milliseconds so uh the question is how far down they are at fifty fifty hertz. Uh. Um.

Yeah. Mm - hmm.

Sorry at twenty - five hertz since they're downsampling by two. So. Does anybody know what the frequency characteristic is?

We don't have yet

Oh OK.

um So, yeah.

OK.

We should have a look first at, perhaps, the modulation spectrum.

Yeah.

Um. So there is this, there is the um length of the filters. Um. So the i this idea of trying to find filters with shorter delays. Um. We started to work with this.

Hmm - hmm.

Mmm. And the third point um was the um, yeah, the on - line normalization where, well, the recursion f recursion for the mean estimation is a filter with some kind of delay

Yeah.

and that's not taken into account right now. Um. Yeah. And there again, yeah. For this, the conclusion of Hynek was, well, " we can try it but "

Uh - huh.

Um.

Try try what?

So try to um um take into account the delay of the recursion for the mean estimation.

OK.

Mmm. And this we've not uh worked on this yet. Um, yeah. And so while discussing about these these LDA filters, some i issues appeared, like well, the fact that if we look at the frequency response of these filters it's uh, well, we don't know really what's the important part in the frequency response and there is the fact that in the very low frequency, these filters don't don't really remove a lot. compared to the to the uh standard RASTA filter. Uh and that's probably a reason why, yeah, on - line normalization helps because it it,

Right.

yeah, it removed this mean. Um. Yeah, but perhaps everything could should be could be in the filter, I mean, uh the the mean normalization and Yeah. So. Yeah. So basically that was that's all we discussed about. We discussed about good things to do also uh well, generally good stuff to do for the research.

Mm - hmm.

And this was this LDA uh tuning perhaps and Hynek proposed again to his uh TRAPS, so.

OK.

Yeah,

I mean I g I guess the key thing for me is is figuring out how to better coordinate between the two sides

um.

cuz because um

Mm - hmm.

uh I was talking with Hynek about it later and the the sort of had the sense sort of that that neither group of people wanted to to bother the other group too much. And and I don't think anybody is, you know, closed in in their thinking or are unwilling to talk about things but I think that you were sort of waiting for them to tell you that they had something for you and and that and expected that they would do certain things and they were sor they didn't wanna bother you

Mm - hmm.

and they were sort of waiting for you and and and uh we ended up with this thing where they they were filling up all of the possible latency themselves, and they just had hadn't thought of that. So. Uh. I mean it's true that maybe maybe no one really thought about that that this latency thing would be such a a strict issue

Yeah. Well, but. Yeah. Yeah. Well.

in in uh the other.

Yeah I don't know what happened really, but

Yeah.

I guess it's it's also so uh the time constraints. Because, well, we discussed about that about this problem and they told us " well, we will do all that's possible to have enough space for a network " but then, yeah, perhaps they were too short with the time and

Then they couldn't. I see.

uh yeah. But there was also problem perhaps a problem of communication. So, yeah. Now we will try to.

Just talk more.

Yeah, slikes and send mails.

Yeah.

u s o o Yeah.

Yeah.

Uh. OK.

So there's um Alright. Well maybe we should just uh I mean you're you're bus other than that you folks are busy doing all the all the things that you're trying that we talked about before right? And this machines are busy and you're busy

Yeah.

and

Basically.

Yeah. OK. Oh.

Um.

Let's let's, I mean, I think that as as we said before that one of the things that we're imagining is that uh there there will be uh in the system we end up with there'll be something to explicitly uh uh do something about noise

Mm - hmm.

in addition to the uh other things that we're talking about and that's probably the best thing to do. And there was that one email that said that it sounded like uh uh things looked very promising up there in terms of uh I think they were using Ericsson's approach or something and in addition to They're doing some noise removal thing, right?

Yeah, yeah. So yeah we're will start to do this also.

Yeah.

Uh so Carmen is just looking at the Ericsson Ericsson code.

Yeah. We modif

Mm - hmm.

And

Yeah, I modified it well, modifying I studied Barry's sim code, more or less. to take @ @ the first step the spectral subtraction. and we have some the feature for Italian database and we will try with this feature with the filter to find the result.

Mm - hmm. Mm - hmm.

But we haven't result until this moment.

Yeah, sure.

But well, we are working in this also

Yeah.

and maybe try another type of spectral subtraction, I don't.

When you say you don't have a result yet you mean it's it's just that it's in process or that you it finished and it didn't get a good result?

No. No, no n we have n we have do the experiment only have the feature the feature but the experiment have

Yeah.

we have not make the experiment

Oh. OK.

and maybe will be good result or bad result, we don't know.

Yeah. Yeah.

Yeah.

OK. So um I suggest actually now we we we sorta move on and and hear what's what's what's happening in in other areas like what's what's happening with your investigations about echos and so on.

Oh um Well um I haven't started writing the test yet, I'm meeting with Adam today

Mm - hmm.

um and he's going t show me the scripts he has for um running recognition on mee Meeting Recorder digits.

Mm - hmm.

Uh I also um haven't got the code yet, I haven't asked Hynek for for the for his code yet. Cuz I looked at uh Avendano's thesis and I don't really understand what he's doing yet but it it it sounded like um the channel normalization part um of his thesis um was done in a a bit of I don't know what the word is, a a bit of a rough way um it sounded like he um he he it it wasn't really fleshed out and maybe he did something that was interesting for the test situation but I I'm not sure if it's what I'd wanna use so I have to I have to read it more, I don't really understand what he's doing yet.

OK. Yeah I haven't read it in a while so I'm not gonna be too much help unless I read it again,

It's my

Oh yeah?

I know this is mine here.

so. OK. Um. The um so you, and then you're also gonna be doing this echo cancelling between the the close mounted and the and the the the what we're calling a cheating experiment uh of sorts between the distant.

Uh I I'm ho Right. Well or I'm hoping I'm hoping Espen will do it.

Ah! OK.

Um

F um

u

Delegate. That's good. It's good to delegate.

I I think he's at least planning to do it for the cl close - mike cross - talk and so maybe I can just take whatever setup he has and use it.

Great. Great. Yeah actually um he should uh I wonder who else is I think maybe it's Dan Ellis is going to be doing uh a different cancellation. Um. One of the things that people working in the meeting task wanna get at is they would like to have cleaner close - miked recordings. So uh this is especially true for the lapel but even for the close close - miked uh cases um we'd like to be able to have um other sounds from other people and so forth removed from So when someone isn't speaking you'd like the part where they're not speaking to actually be So what they're talking about doing is using ec uh echo cancellation - like techniques. It's not really echo but uh just um uh taking the input from other mikes and using uh uh a uh an adaptive filtering approach to remove the effect of that uh other speech. So. Um what was it, there was there was some some some point where eh uh Eric or somebody was was speaking and he had lots of silence in his channel and I was saying something to somebody else uh which was in the background and it was not it was recognizing my words, which were the background speech on the close close mike.

Hmm.

Oh the What we talked about yesterday?

Yes.

Yeah that was actually my I was wearing the I was wearing the lapel and you were sitting next to me,

Oh you it was you I was Yeah.

and I only said one thing but you were talking and it was picking up all your words.

Yeah. Yeah. So they would like clean channels. Uh and for that mmm uh that purpose uh they'd like to pull it out. So I think I think Dan Ellis or somebody who was working with him was going to uh work on that. So. OK. Right? Um. And uh I don't know if we've talked lately about the the plans you're developing that we talked about this morning uh I don't remember if we talked about that last week or not, but maybe just a quick reprise of of what we were saying this morning.

OK.

Uh.

Um.  So continuing to um extend

What about the stuff that um Mirjam has been doing? And and S Shawn, yeah. Oh. So they're training up nets to try to recognize these acoustic features? I see.

But that's uh uh all that's is a a certainly relevant  uh study and, you know, what are the features that they're finding. We have this problem with the overloading of the term " feature " so

Yeah.

uh what are the variables, what we're calling this one, what are the variables that they're found finding useful

Hmm.

um for.

And their their targets are based on canonical mappings of phones to acoustic f features.

Right. And that's certainly one thing to do and we're gonna try and do something more f more fine than that but uh um so um So I guess you know what, I was trying to remember some of the things we were saying, do you ha still have that? Yeah.

Oh yeah.

There's those that uh yeah, some of some of the issues we were talking about was in j just getting a good handle on on uh what " good features " are and.

What does what did um Larry Saul use for it was the sonorant uh detector, right? How did he H how did he do that? Wh - what was his detector? Mm - hmm. Mm - hmm. Oh, OK. Mm - hmm. So how did he combine all these features? What what r mmm classifier did he Hmm. Oh right. You were talking about that, yeah. I see.

And the other thing you were talking about is is is where we get the targets from. So I mean, there's these issues of what are the what are the variables that you use and do you combine them using the soft " AND - OR " or you do something, you know, more complicated um and then the other thing was so where do you get the targets from? The initial thing is just the obvious that we're discussing is starting up with phone labels from somewhere and then uh doing the transformation. But then the other thing is to do something better and eh w why don't you tell us again about this this database? This is the.

Hmm!

And then tell them to talk naturally? Yeah, yeah.

Pierced tongues and Yeah. You could just mount it to that and they wouldn't even notice. Weld it. Zzz.

Maybe you could go to these parlors and and you could, you know you know have have, you know, reduced rates if you if you can do the measurements.

Yeah. I That's right. You could what you could do is you could sell little rings and stuff with embedded you know, transmitters in them and things

Yeah. Yeah, be cool and help science.

and Yeah.

OK.

Hmm! There's a bunch of data that l around, that people have done studies like that w way way back right? I mean I can't remember where uh Wisconsin or someplace that used to have a big database of Yeah. I remember there was this guy at A T - andT, Randolph? or r What was his name? Do you remember that guy? Um, researcher at A T - andT a while back that was studying, trying to do speech recognition from these kinds of features. I can't remember what his name was. Dang. Now I'll think of it. That's interesting.

Do you mean eh but you I mean Mar

Well he was the guy the guy that was using.

you mean when was was Mark Randolph there, or?

Mark Randolph.

Yeah he's he's he's at Motorola now.

Oh is he?

Yeah.

Oh OK.

Yeah.

Yeah.

Is it the guy that was using the pattern of pressure on the tongue or?

I can't remember exactly what he was using, now. But I know I just remember it had to do with you know uh positional parameters

What Yeah.

and trying to m you know do speech recognition based on them.

Mm - hmm.

Yeah. So the only the only uh hesitation I had about it since, I mean I haven't see the data is it sounds like it's it's continuous variables and a bunch of them. And so

Hmm.

I don't know how complicated it is to go from there What you really want are these binary labels, and just a few of them. And maybe there's a trivial mapping if you wanna do it and it's e but it I I I worry a little bit that this is a research project in itself, whereas um if you did something instead that like um having some manual annotation by uh you know, linguistics students, this would there'd be a limited s set of things that you could do a as per our discussions with with John before

Mm - hmm.

but the things that you could do, like nasality and voicing and a couple other things you probably could do reasonably well.

Mm - hmm.

And then there would it would really be uh this uh uh binary variable. Course then, that's the other question is do you want binary variables. So. I mean the other thing you could do is boot trying to to uh get those binary variables and take the continuous variables from uh the uh uh the data itself there, but I I'm not sure.

Could you cluster the just do some kind of clustering?

Guess you could, yeah.

Bin them up into different categories and.

Yeah. So anyway that's that's uh that's another whole direction that cou could be looked at. Um. Um. I mean in general it's gonna be for new data that you look at, it's gonna be hidden variable because we're not gonna get everybody sitting in these meetings to wear the pellets and Um. So.

Right. Right.

So you're talking about using that data to get uh instead of using canonical mappings of phones.

Right.

So you'd use that data to give you sort of what the the true mappings are for each phone?

Mm - hmm.

I see.

Mm - hmm.

Yeah. So wh yeah, where this fits into the rest in in my mind, I guess, is that um we're looking at different ways that we can combine uh different kinds of of rep front - end representations um in order to get robustness under difficult or even, you know, typical conditions. And part of it, this robustness, seems to come from uh multi - stream or multi - band sorts of things and Saul seems to have a reasonable way of looking at it, at least for one one um articulatory feature. The question is is can we learn from that to change some of the other methods we have, since I mean, one of the things that's nice about what he had I thought was that that it it um the decision about how strongly to train the different pieces is based on uh a a reasonable criterion with hidden variables rather than um just assuming that you should train e e every detector uh with equal strength towards uh it being this phone or that phone. Right? So it so um he's got these um uh uh

Hmm.

he " AND's " between these different features. It's a soft " AND ", I guess but in in principle you you wanna get a strong concurrence of all the different things that indicate something and then he " OR's " across the different soft " OR's " across the different uh multi - band channels. And um the weight yeah, the target for the training of the " AND " " AND' ed " things is something that's kept uh as a hidden variable, and is learned with EM. Whereas what we were doing is is uh taking the phone target and then just back propagating from that

So he doesn't have.

which means that it's it's uh i It could be for instance that for a particular point in the data you don't want to um uh train a particular band train the detectors for a particular band. You you wanna ignore that band, cuz that's a Ban - band is a noisy noisy measure.

Mm - hmm.

And we don't We're we're still gonna try to train it up. In our scheme we're gonna try to train it up to do as well well as it can at predicting. Uh. Maybe that's not the right thing to do.

So he doesn't have to have truth marks or Ho

F right, and uh he doesn't have to have hard labels.

Well at the at the tail end, yeah, he has to know what's where it's sonorant. But he's but what he's - but what he's not training up uh what he doesn't depend on as truth is

Right. For the full band.

um I guess one way of describing would be if if a sound is sonorant is it sonorant in this band? Is it sonorant in that band?

Right.

Is it sonorant in that band? i It's hard to even answer that what you really mean is that the whole sound is sonorant. So

Mm - hmm. OK.

then it comes down to, you know, to what extent should you make use of information from particular band towards making your decision. And um uh we're making in a sense sort of this hard decision that you should you should use everything uh with with uh equal strength.

I see.

And uh because in the ideal case we would be going for posterior probabilities, if we had uh enough data to really get posterior probabilities and if the if we also had enough data so that it was representative of the test data then we would in fact be doing the right thing to train everything as hard as we can. But um this is something that's more built up along an idea of robustness from from the beginning and so you don't necessarily want to train everything up towards the.

So where did he get his uh his tar his uh high - level targets about what's sonorant and what's not?

From uh canonical mappings  um at first

OK.

Yeah.

and then it's unclear um eh

Using TIMIT? or using.

using TIMIT

Uh - huh.

right, right.

Yeah.

And then uh he does some fine tuning um for um special cases. Yeah.

Yeah. I mean we ha we have a kind of iterative training because we do this embedded Viterbi, uh so there is some something that's suggested, based on the data but it's it's not I think it s doesn't seem like it's quite the same, cuz of this cuz then whatever that alignment is, it's that for all all bands.

Mm - hmm.

Well no, that's not quite right, we did actually do them separate tried to do them separately so that would be a little more like what he did. Um. But it's still not quite the same because then it's it's um setting targets based on where you would say the sound begins in a particular band. Where he's s this is not a labeling per se. Might be closer I guess if we did a soft soft target uh uh embedded neural net training like we've done a few times uh f the forward um do the forward calculations to get the gammas and train on those. Mmm. Uh what's next?

I could say a little bit about w stuff I've been playing with.

Oh. You're playing?

I um Huh?

You're playing?

Yes, I'm playing. Um so I wanted to do this experiment to see um uh what happens if we try to uh improve the performance of the back - end recognizer for the Aurora task and see how that affects things. And so I had this um I think I sent around last week a this plan I had for an experiment, this matrix where I would take the um the original um the original system. So there's the original system trained on the mel cepstral features and then com and then uh optimize the b HTK system and run that again. So look at the difference there and then uh do the same thing for the ICSI - OGI front - end.

What which test set was this?

This is that I looked at?

Mm - hmm.

Uh I'm looking at the Italian right now.

Mm - hmm.

So as far as I've gotten is I've uh been able to go through from beginning to end the um full HTK system for the Italian data and got the same results that um that uh Stephane had. So um I started looking to and now I'm I'm sort of lookin at the point where I wanna know what should I change in the HTK back - end in order to try to uh to improve it. So. One of the first things I thought of was the fact that they use the same number of states for all of the models

Mm - hmm.

and so I went on - line and I uh found a pronunciation dictionary for Italian digits

Mm - hmm.

and just looked at, you know, the number of phones in each one of the digits. Um you know, sort of the canonical way of setting up a an HMM system is that you use um three states per phone and um so then the the total number of states for a word would just be, you know, the number of phones times three. And so when I did that for the Italian digits, I got a number of states, ranging on the low end from nine to the high end, eighteen. Um. Now you have to really add two to that because in HTK there's an initial null and a final null so when they use uh models that have eighteen states, there're really sixteen states. They've got those initial and final null states. And so um their guess of eighteen states seems to be pretty well matched to the two longest words of the Italian digits, the four and five which um, according to my, you know, sort of off the cuff calculation, should have eighteen states each.

Mm - hmm.

And so they had sixteen. So that's pretty close. Um but for the most of the words are sh much shorter. So the majority of them wanna have nine states. And so theirs are s sort of twice as long. So my guess uh And then if you I I printed out a confusion matrix um uh for the well - matched case, and it turns out that the longest words are actually the ones that do the best. So my guess about what's happening is that you know, if you assume a fixed the same amount of training data for each of these digits and a fixed length model for all of them but the actual words for some of them are half as long you really um have, you know, half as much training data for those models. Because if you have a long word and you're training it to eighteen states, uh you've got you know, you've got the same number of Gaussians, you've gotta train in each case,

Mm - hmm.

but for the shorter words, you know, the total number of frames is actually half as many.

Mm - hmm.

So it could be that, you know, for the short words there's because you have so many states, you just don't have enough data to train all those Gaussians. So um I'm going to try to um create more word - specific um uh prototype H M Ms to start training from.

Yeah, I mean, it's not at all uncommon you do worse on long word on short words than long words anyway just because you're accumulating more evidence for the for the longer word,

Mm - hmm.

but.

Yeah so I'll I'll, the next experiment I'm gonna try is to just um you know create uh models that seem to be more w matched to my guess about how long they should be.

Mm - hmm.

And as part of that um I wanted to see sort of how the um how these models were coming out, you know, what w when we train up uh th you know, the model for " one ", which wants to have nine states, you know, what is the uh what do the transition probabilities look like in the self - loops,  look like in in those models? And so I talked to Andreas and he explained to me how you can calculate the expected duration of an HMM just by looking at the transition matrix

Mm - hmm.

and so I wrote a little Matlab script that calculates that and so I'm gonna sort of print those out for each of the words to see what's happening, you know, how these models are training up,

Mm - hmm. Mm - hmm.

you know, the long ones versus the short ones. I d I did quickly, I did the silence model and and um that's coming out with about one point two seconds as its average duration and the silence model's the one that's used at the beginning and the end of each of the string of digits.

Wow. Lots of silence.

Yeah, yeah. And so the S P model, which is what they put in between digits, I I haven't calculated that for that one yet, but um. So they basically their their model for a whole digit string is silence digit, SP, digit, SP blah - blah - blah and then silence at the end. And so.

Are the SP's optional? I mean skip them?

I have to look at that, but I'm not sure that they are. Now the one thing about the S P model is really it only has a single s emitting state to it.

Mm - hmm.

So if it's not optional, you know, it's it's not gonna hurt a whole lot

I see.

and it's tied to the center state of the silence model so it's not its own um It doesn't require its own training data,

Mm - hmm.

it just shares that state.

Mm - hmm.

So it, I mean, it's pretty good the way that they have it set up, but um i So I wanna play with that a little bit more. I'm curious about looking at, you know how these models have trained and looking at the expected durations of the models and I wanna compare that in the the well - matched case f to the unmatched case, and see if you can get an idea of just from looking at the durations of these models, you know, what what's happening.

Yeah, I mean, I think that uh, as much as you can, it's good to d sort of not do anything really tricky.

Mm - hmm.

Not do anything that's really finely tuned, but just sort of eh you know you t you i z

Yeah.

The premise is kind of you have a a good person look at this for a few weeks and what do you come up with?

Mm - hmm. Mm - hmm.

And uh

And Hynek, when I wa told him about this, he had an interesting point, and that was th um the the final models that they end up training up have I think probably something on the order of six Gaussians per state. So they're fairly, you know, hefty models. And Hynek was saying that well, probably in a real application, you wouldn't have enough compute to handle models that are very big or complicated. So in fact what we may want are simpler models.

Could be.

And compare how they perform to that. But you know, it depends on what the actual application is and it's really hard to know what your limits are in terms of how many Gaussians you can have.

Right. And that, I mean, at the moment that's not the limitation, so.

Mm - hmm.

I mean, I I I what I thought you were gonna say i but which I was thinking was um where did six come from? Probably came from the same place eighteen came from. You know, so.

Yeah. Right.

Uh that's another parameter, right? that that maybe, you know, uh you really want three or nine or.

Yeah, yeah. Well one thing I mean, if I if if I start um reducing the number of states for some of these shorter models that's gonna reduce the total number of Gaussians.

Right.

So in a sense it'll be a simpler system.

Yeah. Yeah. But I think right now again the idea is doing just very simple things

Yeah.

how much better can you make it? And um since they're only simple things there's nothing that you're gonna do that is going to blow up the amount of computation

Mm - hmm.

um so

Right. Right.

if you found that nine was better than six that would be O K, I think, actually.

Mm - hmm.

Doesn't have to go down.

Yeah. I really wasn't even gonna play with that part of the system yet,

Mm - hmm, OK.

I was just gonna change the the t

Yeah, just work with the models, yeah.

yeah, just look at the length of the models and just see what happens.

Yeah.

So.

Cool. OK. So uh what's uh I guess your plan for You you you guys' plan for the next next week is just continue on these these same things we've been talking about for Aurora and

Yeah, I guess we can try to have some kind of new baseline for next week perhaps. with all these minor things modified. And then do other things, play with the spectral subtraction, and retry the MSG and things like that.

Yeah. Yeah. Yeah we we have a big list.

Big list?

You have a big list of of things to do. So. Well that's good. I think that after all of this uh um confusion settles down in another some point a little later next year there will be some sort of standard and it'll get out there and hopefully it'll have some effect from something that that has uh been done by our group of people but uh e even if it doesn't there's there's go there'll be standards after that. So.

Does anybody know how to um run Matlab sort of in batch mode like you c send it s a bunch of commands to run and it gives you the output. Is it possible to do that?

I I think uh Mike tried it

Yeah?

and he says it's impossible so he went to Octave.

Octave.

Octave is the um UNIX clone of of Matlab which you can batch.

Ah! OK. Great. Thanks.

Yeah.

I was going crazy trying to do that.

Huh.

Yeah.

What is Octave so? It's a free software?

What's that? Uh, Octave?

Yeah.

Yeah it's it's it's free. I think we have it here  r running somewhere.

Great!

Yeah.

And it does the same syntax and everything eh like Matlab, or?

Um  i it's a little behind, it's the same syntax but it's a little behind in that  Matlab went to these like um you can have cells and you can you can  uh implement object - oriented type things with Matlab. Uh Octave doesn't do that yet, so I think you, Octave is kinda like Matlab um four point something or.

If it'll do like a lot of the basic matrix and vector stuff

The basic stuff, right.

that's perfect.

Yeah.

Great!

OK, guess we're done.

OK.

Well, although by the way.

Question: What were the main things that were talked about during the meeting?

Response:
Here are some topics that were discussed during the meeting:

* The issues with the downsampling problem of the feature vector data stream.
* The choice of filter length.
* The online normalization process where the recursion for mean estimation forms a filter with a delay.
* Tuning the LDA filters.
* Conducting echo cancellation and noise reduction experiments.
* Integration of acoustic features to canonical mappings of phones to improve the robustness of the speech recognition.

Question: What was their conclusion about the downsampling problem?

Response: They did not come to any conclusions at the meeting regarding the downsampling problem. Instead, the participants agreed to try implementing a stricter downsampling method.

Question: What did Professor A say about robustness with multi-stream information combination?

Response: Professor A said that they are looking at different ways that they can combine different kinds of rep front-end representations to get robustness under difficult or even, typical conditions. And part of it, this robustness, seems to come from multi-stream or multi-band sorts of things.

Question: What conclusion was reached regarding the online normalization process?

Response: The participants had not come to any conclusions regarding the online normalization process during the meeting. Instead, they decided to try taking into account the delay of the recursion for mean estimation through modifying the TRAPS.

Question: What conclusions were reached regarding the LDA filter tuning?

Response:
The participants had not yet drawn any conclusions regarding the tuning of the LDA filters. However, they discussed the following issues related to the filters:
* The frequency response of the filters is not clear.
* For very low frequencies, the filters do not remove as much as the standard RASTA filter.
* Perhaps the mean normalization and the online normalization could be implemented in the filter.

Question: What was their conclusion on the integration of acoustic features to canonical mappings of phones?

Response: The participants did not decide anything regarding the integration of acoustic features to canonical mappings of phones. However, they discussed to integrate the acoustic features to canonical mappings of phones to improve the robustness of the speech recognition.

Question: Why did they decide to try using a stricter downsampling method?

Response: The meeting participants discussed the downsampling problem of the feature vector data stream. To address this issue, they all agreed to try implementing a stricter downsampling method.

Question: Besides the downsampling issue, what other options did they consider to improve the robustness of the speech recognition multi-stream information combination?

Response: During the meeting, improving the robustness of the speech recognition system through multi-stream information combination was discussed. Saul has done research on combining different types of front-end representations to improve robustness under various conditions. One of the strengths of his approach is that the decision about how strongly to train different detectors is based on a reasonable hidden variable criterion.

Question: What was decided regarding the perceptual masking experiment?

Response: There is no mention of any perceptual masking experiment in the provided meeting transcript.

Question: Did the participants identify other issues they wanted to address at a later meeting, aside from those already mentioned?

Response: The transcript does not contain any information regarding a perceptual masking experiment. Therefore, I cannot answer your question.
