Correction: Browser Agent SDK has no client-side VAD
By Steven Van ·
Deepgram says client-side Silero VAD was documented but never shipped in the Browser Agent SDK; barge-in runs server-side instead.
Deepgram has corrected its Browser Agent SDK documentation: the client-side Silero voice activity detection it described was never actually shipped in any released package.
None of the following ever existed:
- The vad option on MicrophoneOptions in @deepgram/agents
- The speechThreshold and silenceThreshold VAD options
- The speech-start and speech-end events on AgentMicrophone
- The vad field in WidgetConfig and the widget's VAD configuration section
- The @ricky0123/vad-web and onnxruntime-web peer dependencies (uninstall them if you added them for VAD)
MicrophoneOptions actually accepts sampleRate, echoCancellation, noiseSuppression, and autoGainControl, and the microphone streams continuously while unmuted. Barge-in still works, but it's driven server-side: the Voice Agent API emits a user-started-speaking event, which apps pair with player.interrupt() to stop playback. Deepgram
