Can I use speaker diarization with Streaming Speech-to-Text?

Yes. Streaming Diarization is supported on all streaming models, including u3-rt-pro, universal-streaming-english, universal-streaming-multilingual, and whisper-rt. Enable it by adding speaker_labels: true to your connection parameters. See our Streaming Diarization documentation to learn more.

Alternatively, you can use multichannel audio (i.e., an audio stream for each speaker) to separate speakers by creating a separate session for each channel. See the Multichannel streaming audio section for details on this approach.
