Version 3.1.1 (2023-12-01)

TL;DR

Providing num_speakers to pyannote/speaker-diarization-3.1 now works as expected.

Fixes

• fix(pipeline): fix support for setting num_speakers in pyannote/speaker-diarization-3.1 pipeline

Version 3.1.0 (2023-11-16)

TL;DR

pyannote/speaker-diarization-3.1 no longer requires unpopular ONNX runtime

New features

• feat(model): add WeSpeaker embedding wrapper based on PyTorch
• feat(model): add support for multi-speaker statistics pooling
• feat(pipeline): add TimingHook for profiling processing time
• feat(pipeline): add ArtifactHook for saving internal steps

Improvements

Breaking changes

• BREAKING(pipeline): rename WeSpeakerPretrainedSpeakerEmbedding to ONNXWeSpeakerPretrainedSpeakerEmbedding
• BREAKING(setup): remove onnxruntime dependency. You can still use ONNX hbredin/wespeaker-voxceleb-resnet34-LM but you will have to install onnxruntime yourself.
• BREAKING(pipeline): remove logging_hook (use ArtifactHook instead)
• BREAKING(pipeline): remove onset and offset parameter in SpeakerDiarizationMixin.speaker_count You should now binarize segmentations before passing them to speaker_count

Version 3.0.1 (2023-09-28)

• fix(pipeline): fix WeSpeaker GPU support

Version 3.0.0 (2023-09-26)

Features and improvements

• feat(pipeline): send pipeline to device with pipeline.to(device)
• feat(pipeline): add return_embeddings option to SpeakerDiarization pipeline
• feat(pipeline): make segmentation_batch_size and embedding_batch_size mutable in SpeakerDiarization pipeline (they now default to 1)

• feat(task): add powerset support to SpeakerDiarization task
• feat(task): add support for multi-task models
• feat(task): add support for label scope in speaker diarization task

• improve(task): load metadata as tensors rather than pyannote.core instances
• improve(task): improve error message on missing specifications

Breaking changes

• BREAKING(task): rename Segmentation task to SpeakerDiarization
• BREAKING(pipeline): pipeline defaults to CPU (use pipeline.to(device))
• BREAKING(pipeline): remove SpeakerSegmentation pipeline (use SpeakerDiarization pipeline)

• BREAKING(setup): drop support for Python 3.7
• BREAKING(io): channels are now 0-indexed (used to be 1-indexed)
• BREAKING(io): multi-channel audio is no longer downmixed to mono by default. You should update how pyannote.audio.core.io.Audio is instantiated:
  • replace Audio() by Audio(mono="downmix");
  • replace Audio(mono=True) by Audio(mono="downmix");
  • replace Audio(mono=False) by Audio().
• BREAKING(model): get rid of (flaky) Model.introspection If, for some weird reason, you wrote some custom code based on that, you should instead rely on Model.example_output.
