speaker-diarization-3.1

Pyannote speaker-diarization-3.1 is a complete speaker diarization pipeline from pyannote.audio that answers 'who spoke when' in an audio recording. It segments audio into speaker-homogeneous regions, clusters them by speaker identity using embedding models, and outputs timestamped speaker labels. Used in meeting transcription, podcast editing, and call center analytics.

Use cases

  • Meeting recording segmentation by speaker for per-speaker transcription
  • Podcast and interview audio segmentation for editing workflows
  • Call center audio analytics requiring per-speaker turn identification
  • Research transcription where speaker attribution is required
  • Pre-processing step before speaker-labeled ASR

Pros

  • Complete end-to-end pipeline covering VAD, segmentation, embedding, and clustering
  • MIT license for commercial use
  • Well-maintained pyannote ecosystem with active research updates
  • State-of-the-art diarization error rates on standard benchmarks

Cons

  • Requires accepting pyannote model terms on HuggingFace — not automatic download
  • Performance degrades significantly with overlapping speech segments
  • Number of speakers must be estimated or provided; errors cascade to final output
  • GPU recommended for real-time processing; CPU inference is slow on long recordings
  • Hyperparameter tuning (clustering threshold, min/max speakers) required per domain
