Included review availability: Your plan provides up to 1 included review per hour; 0 remain after this review. 📝 WalkthroughWalkthroughThe change adds web and native speaking-while-muted recognition, Apple ADM microphone mute support, mute-state preservation during audio suspension, and a configurable mute strategy. It also comments out token-provider code and updates WebRTC dependency constraints. ChangesAudio recognition and microphone mute control
Commented token-provider design
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This change adds speaking-while-muted behavior and changes microphone mute/resume handling, but concurrent mute and audio-resume operations may briefly reactivate the microphone, and a failed resume may leave audio only partially restored. Detection can also be lost or unnecessarily restarted after stream or device changes. The PR is not merge-ready until these bounded lifecycle and recovery risks are fixed or explicitly accepted.

{'deviceId': {'exact': deviceId}}.

- Around line 38-64: The _events.listen subscription in _startRecognition
currently does not handle asynchronous errors from the custom
speechActivityStream. Add an onError callback that stops recognition and
performs the existing cleanup/state reset path when the stream fails, while
preserving the started and ended event handling.
In
`@packages/stream_video/lib/src/audio_processing/speaking_while_muted_recognition.dart`:
- Around line 136-143: Update the start-request path so
_activeAudioInputDeviceId is assigned when start() records _shouldRun, before
any queued _startRecognition transition can execute. Keep the existing
device-change comparison and _restart() behavior unchanged, while avoiding false
changes caused by the previous device id remaining until recognition starts.
In `@packages/stream_video/lib/src/call/session/call_session.dart`:
- Around line 1280-1293: The neverStarted resume path must not restart a
currently muted local microphone track when stopTrackOnMute is false. Update the
resume logic around RtcLocalTrack.start() to detect muted local microphone
tracks via _isMutedLocalMicrophoneTrack(track), leave them disabled, and
preserve the existing ADM mute behavior.
