Using pyannote.audio open-source toolkit in production? Make the most of it thanks to our consulting services.

pyannote.audio speaker diarization toolkit

pyannote.audio is an open-source toolkit written in Python for speaker diarization. Based on PyTorch machine learning framework, it comes with state-of-the-art pretrained models and pipelines, that can be further finetuned to your own data for even better performance.

TL;DR

1. Install pyannote.audio with pip install pyannote.audio
2. Accept pyannote/segmentation-3.0 user conditions
3. Accept pyannote/speaker-diarization-3.1 user conditions
4. Create access token at hf.co/settings/tokens.

from pyannote.audio import Pipeline
pipeline = Pipeline.from_pretrained(
    "pyannote/speaker-diarization-3.1",
    use_auth_token="HUGGINGFACE_ACCESS_TOKEN_GOES_HERE")

# send pipeline to GPU (when available)
import torch
pipeline.to(torch.device("cuda"))

# apply pretrained pipeline
diarization = pipeline("audio.wav")

# print the result
for turn, _, speaker in diarization.itertracks(yield_label=True):
    print(f"start={turn.start:.1f}s stop={turn.end:.1f}s speaker_{speaker}")
# start=0.2s stop=1.5s speaker_0
# start=1.8s stop=3.9s speaker_1
# start=4.2s stop=5.7s speaker_0
# ...

Benchmark

Out of the box, pyannote.audio speaker diarization pipeline v3.1 is expected to be much better (and faster) than v2.x. Those numbers are diarization error rates (in %):

Benchmark	v2.1	v3.1	Premium
AISHELL-4	14.1	12.3	11.9
AliMeeting (channel 1)	27.4	24.5	22.5
AMI (IHM)	18.9	18.8	16.6
AMI (SDM)	27.1	22.6	20.9
AVA-AVD	66.3	50.0	39.8
CALLHOME (part 2)	31.6	28.4	22.2
DIHARD 3 (full)	26.9	21.4	17.2
Ego4D (dev.)	61.5	51.2	43.8
MSDWild	32.8	25.4	19.8
REPERE (phase2)	8.2	7.8	7.6
VoxConverse (v0.3)	11.2	11.2	9.4
