BrowserVadProviderOptions

Defined in: packages/realtime-vad/dist/browser-vad.types.d.ts:14

Detection tuning passed through to the VAD provider.

This is an allowlist, not a partial of the provider’s options. Streams, callbacks, lifecycle, asset paths, audio contexts, ONNX Runtime configuration, and start policy stay adapter-owned.

Stricter thresholds cut false starts and begin missing quiet speech. Longer silence handling preserves natural pauses and delays the end of every turn. Tune against representative speakers, microphones, browsers, playback volume, and background noise.
