Usage

Voice activity detection

python

from pyannote.audio.pipelines import VoiceActivityDetection
pipeline = VoiceActivityDetection(segmentation="pyannote/segmentation")
HYPER_PARAMETERS = {
  # onset/offset activation thresholds
  "onset": 0.5, "offset": 0.5,
  # remove speech regions shorter than that many seconds.
  "min_duration_on": 0.0,
  # fill non-speech regions shorter than that many seconds.
  "min_duration_off": 0.0
}
pipeline.instantiate(HYPER_PARAMETERS)
vad = pipeline("audio.wav")
# `vad` is a pyannote.core.Annotation instance containing speech regions

Overlapped speech detection

python

from pyannote.audio.pipelines import OverlappedSpeechDetection
pipeline = OverlappedSpeechDetection(segmentation="pyannote/segmentation")
pipeline.instantiate(HYPER_PARAMETERS)
osd = pipeline("audio.wav")
# `osd` is a pyannote.core.Annotation instance containing overlapped speech regions

Resegmentation

python

from pyannote.audio.pipelines import Resegmentation
pipeline = Resegmentation(segmentation="pyannote/segmentation", 
                          diarization="baseline")
pipeline.instantiate(HYPER_PARAMETERS)
resegmented_baseline = pipeline({"audio": "audio.wav", "baseline": baseline})
# where `baseline` should be provided as a pyannote.core.Annotation instance

Raw scores

python

from pyannote.audio import Inference
inference = Inference("pyannote/segmentation")
segmentation = inference("audio.wav")
# `segmentation` is a pyannote.core.SlidingWindowFeature
# instance containing raw segmentation scores like the 
# one pictured above (output)

Reproducible research

In order to reproduce the results of the paper "End-to-end speaker segmentation for overlap-aware resegmentation ", use the following hyper-parameters:

Voice activity detection	`onset`	`offset`	`min_duration_on`	`min_duration_off`
AMI Mix-Headset	0.684	0.577	0.181	0.037
DIHARD3	0.767	0.377	0.136	0.067
VoxConverse	0.767	0.713	0.182	0.501

Overlapped speech detection	`onset`	`offset`	`min_duration_on`	`min_duration_off`
AMI Mix-Headset	0.448	0.362	0.116	0.187
DIHARD3	0.430	0.320	0.091	0.144
VoxConverse	0.587	0.426	0.337	0.112

Resegmentation of VBx	`onset`	`offset`	`min_duration_on`	`min_duration_off`
AMI Mix-Headset	0.542	0.527	0.044	0.705
DIHARD3	0.592	0.489	0.163	0.182
VoxConverse	0.537	0.724	0.410	0.563

Expected outputs (and VBx baseline) are also provided in the /reproducible_research sub-directories.
