Open the original- What it measures
- WhisperX is a third-party project built on Whisper, not an OpenAI product. Its README describes diarization as a feature of the pipeline.
- What it does not show
- The README does not give diarization accuracy. Diarization uses a separate model from pyannote-audio, which needs a Hugging Face access token.
