VoxCeleb plugin for pyannote.database

This package provides an implementation of the speaker verification protocols used in the VoxCeleb paper.

Installation

  • Install this package
$ pip install pyannote.db.voxceleb
/path/to/voxceleb/voxceleb1/dev/wav/id10001/1zcIwhmdeo4/00001.wav
/path/to/voxceleb/voxceleb1/test/wav/id10270/5r0dWxy17C8/00001.wav
/path/to/voxceleb/voxceleb2/dev/aac/id00012/21Uxsk56VDQ/00001.m4a
/path/to/voxceleb/voxceleb2/test/aac/id00017/01dfn2spqyE/00001.m4a

Databases:

  VoxCeleb:
    - /path/to/voxceleb/voxceleb1/dev/wav/{uri}.wav
    - /path/to/voxceleb/voxceleb1/test/wav/{uri}.wav
    - /path/to/voxceleb/voxceleb2/dev/aac/{uri}.wav
    - /path/to/voxceleb/voxceleb2/test/aac/{uri}.wav

Note that m4a files from VoxCeleb 2 have to be converted to wav for pyannote.audio to handle them nicely.

Usage

We start by initializing VoxCeleb2 speaker verification protocol.

from pyannote.database import get_protocol
protocol = get_protocol('VoxCeleb.SpeakerVerification.VoxCeleb2')

One can use protocol.train generator to train the background model.

for training_file in protocol.train():
    uri = training_file['uri']
    print('Current filename is {0}.'.format(uri))

    # "who speaks when" as a pyannote.core.Annotation instance
    annotation = training_file['annotation']
    for segment, _, speaker in annotation.itertracks(yield_label=True):
        print('{0} speaks between t={1:.1f}s and t={2:.1f}s.'.format(
            speaker, segment.start, segment.end))
   
    break  # this should obviously be replaced
           # by the actual background training

Use protocol.test_trial to iterate over all test trials:

for t, trial in enumerate(protocol.test_trial()):
    
    file1 = trial['file1']    
    file2 = trial['file2']    
    same = trial['reference']
    
    msg = f"{file1['uri']} vs. {file2['uri']} {'same' if same else 'different'}"
    print(msg)
    
    if t > 10:
        break

Here is how to get the list of all available speaker verification protocols.

from pyannote.database import get_database
voxceleb = get_database('VoxCeleb')

for protocol_name in voxceleb.get_protocols('SpeakerVerification'):
    print(f'VoxCeleb.SpeakerVerification.{protocol_name}')
