+- `SpeechTimeoutUserTurnStopStrategy` now waits only `user_speech_timeout` when a transcript arrives without a VAD stop event, rather than `max(ttfs_p99_latency, user_speech_timeout)`. If you had `ttfs_p99_latency > user_speech_timeout`, turn detection in that path is slightly faster than before.

+- 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.
