# 🎹 Speaker diarization |
|
|
|
Relies on pyannote.audio 2.0: see [installation instructions](https://github.com/pyannote/pyannote-audio/tree/develop#installation). |
|
|
|
|
|
## TL;DR |
|
|
|
```python |
|
# load the pipeline from Hugginface Hub |
|
from pyannote.audio import Pipeline |
|
pipeline = Pipeline.from_pretrained("pyannote/speaker-diarization@2022.07") |
|
|
|
# apply the pipeline to an audio file |
|
diarization = pipeline("audio.wav") |
|
|
|
# dump the diarization output to disk using RTTM format |
|
with open("audio.rttm", "w") as rttm: |
|
diarization.write_rttm(rttm) |
|
``` |
|
|
|
## Advanced usage |
|
|
|
In case the number of speakers is known in advance, one can use the `num_speakers` option: |
|
|
|
```python |
|
diarization = pipeline("audio.wav", num_speakers=2) |
|
``` |
|
|
|
One can also provide lower and/or upper bounds on the number of speakers using `min_speakers` and `max_speakers` options: |
|
|
|
```python |
|
diarization = pipeline("audio.wav", min_speakers=2, max_speakers=5) |
|
``` |
|
|
|
If you feel adventurous, you can try and play with the various pipeline hyper-parameters. |
|
For instance, one can use a more aggressive voice activity detection by increasing the value of `segmentation_onset` threshold: |
|
|
|
```python |
|
hparams = pipeline.parameters(instantiated=True) |
|
hparams["segmentation_onset"] += 0.1 |
|
pipeline.instantiate(hparams) |
|
``` |
|
|
|
## Benchmark |
|
|
|
### Real-time factor |
|
|
|
Real-time factor is around 5% using one Nvidia Tesla V100 SXM2 GPU (for the neural inference part) and one Intel Cascade Lake 6248 CPU (for the clustering part). |
|
|
|
In other words, it takes approximately 3 minutes to process a one hour conversation. |
|
|
|
### Accuracy |
|
|
|
This pipeline is benchmarked on a growing collection of datasets. |
|
|
|
Processing is fully automatic: |
|
|
|
* no manual voice activity detection (as is sometimes the case in the literature) |
|
* no manual number of speakers (though it is possible to provide it to the pipeline) |
|
* no fine-tuning of the internal models nor tuning of the pipeline hyper-parameters to each dataset |
|
|
|
... with the least forgiving diarization error rate (DER) setup (named *"Full"* in [this paper](https://doi.org/10.1016/j.csl.2021.101254)): |
|
|
|
* no forgiveness collar |
|
* evaluation of overlapped speech |
|
|
