Crate wavekat_turn 

wavekat-turn

Unified turn detection with multiple backends.

Provides a clean abstraction over turn-detection models that predict whether a user has finished speaking. Two trait families cover the two fundamental input modalities:

• AudioTurnDetector — operates on raw audio frames (e.g. Pipecat Smart Turn)
• TextTurnDetector — operates on ASR transcript text (e.g. LiveKit EOU)

For most use cases, wrap a detector in TurnController to get automatic state tracking and soft-reset logic for VAD integration. See controller for details.
