### MF: Male/Female for Forced Phonetic Alignment

This is a two-speaker dataset manually aligned at the phoneme level (Praat's
textgrid files provided). Each portion contains 200 instances from both a male
and a female speaker. This repo has been used as ground truth for the following
papers:

One major problem with both male and female datasets is that they were hand
aligned according to an unknown phoneset, which nobody really knows where it
actually came from. So it required some considerable amount of processing in
order to convert the original phoneset to the FalaBrasil phoneset, since the
latter is the one which all acoustic models are trained over.

Dataset original phone set:

```bash
$ find male/textgrid -name "*.TextGrid" > filelist
$ while read line ; do awk '/phones/,/syll/' $line | grep 'text =' | awk '{print $3}' ; done < filelist | sort | uniq | sed 's/"//g'

```

FalaBrasil original phone set (see also our
[NLP Generator](https://gitlab.com/fb-nlp/nlp-generator) library, which
performs the G2P conversion):

```bash
$ find male/textgrid_falabrasil -name "*.TextGrid" > filelist
$ while read line ; do awk '/"phones"/,/"syllphones"/' $line | grep 'text =' | awk '{print $3}' ; done < filelist | sort | uniq | sed 's/"//g'
