• If you use an STT service that emits finalized transcripts (Speechmatics, Soniox, Deepgram Flux, AssemblyAI) with SpeechTimeoutUserTurnStopStrategy, user turns now end as soon as user_speech_timeout elapses after VAD stop. Previously the strategy also waited for the STT P99 latency (ttfs_p99_latency) even when the transcript was already marked final. user_speech_timeout is still honored as a floor — STT finalization never shortens it.
