# Pyannote-audio : Speaker Diarization

## Input

Audio file (.wav format).
```
Example
input: data/demo.wav
```
(Wav file from https://github.com/pyannote/pyannote-audio/tree/develop/pyannote/audio/sample)

## Output

When and who spoke.

```
[ 00:00:06.714 -->  00:00:07.003] A speaker91
[ 00:00:07.003 -->  00:00:07.173] B speaker90

[ 00:00:14.303 -->  00:00:17.886] G speaker91
[ 00:00:18.022 -->  00:00:21.502] H speaker90
[ 00:00:18.157 -->  00:00:18.446] I speaker91
[ 00:00:21.774 -->  00:00:28.531] J speaker91
[ 00:00:27.886 -->  00:00:29.991] K speaker90
```

## Requirements

This model recommends additional module.
```bash
$ pip3 install -r requirements.txt
```

## Usage

Automatically downloads the onnx and prototxt files on the first run.
It is necessary to be connected to the Internet while downloading.

For the sample
```bash
$ python pyannote-audio.py -i ./data/sample.wav
```

For the sample with plot
```bash
$ python pyannote-audio.py -i ./data/sample.wav --plt
```

For the sample with verification
```bash
$ python pyannote-audio.py -i ./data/sample.wav -g ./data/sample.rttm
```

If you want to specify the audio, put the file path after the `--i` or `-input` option.

```bash
$ python pyannote-audio.py --i FILE_PATH
```

If you want to specify the ground truth, put the file path after the `--ig` or `-input_ground` option.

```bash
$ python pyannote-audio.py --ig FILE_PATH
```

If you want to specify the output file, put the file path after the `--o` or `-output` option.

```bash
$ python pyannote-audio.py --o FILE_PATH
```

If you want to specify the output ground truth file, put the file path after the `--og` or `-output_ground` option.

```bash
$ python pyannote-audio.py --og FILE_PATH
```

If you know the number of speakers, put the numper　`--num` or `-num_speaker` option.
```bash
$ python pyannote-audio.py --num 2
```

If you know the maxisimum number of speakers, put the numper　`--max` or `-max_speaker` option.
```bash
$ python pyannote-audio.py --max 4
```

If you know the minimum number of speakers, put the numper　`--min` or `-min_speaker` option.
```bash
$ python pyannote-audio.py --min 2
```

By giving the `--e` or `-error` option, you can get diarization error rate.
```bash
$ python pyannote-audio.py --use_onnx
```

By giving the `--plt` option, you can visualize results.
```bash
$ python pyannote-audio.py --use_onnx
```

By giving the `--use_onnx` option, you can use onnx.
```bash
$ python pyannote-audio.py --use_onnx
```

By giving the `--embed` option, you can get embedding vector in the input file.
```bash
$ python pyannote-audio.py --embed
```
