feat(streaming): add acknowledgeSilence param and silence event - #185
Merged
Merged
Conversation
Add the `acknowledgeSilence` opt-in to `StreamingTranscriberParams` (sent as `acknowledge_silence`) and to `StreamingUpdateConfiguration` for mid-stream changes. When enabled (U3Pro only), the server emits a `Silence` message roughly once per second while no speech is being transcribed. Add the matching `SilenceEvent` type (`start_ms`/`end_ms`), a `silence` event with an `on()` overload, the inbound switch case, and unit tests. Bump version to 4.41.2 and add the changelog entry.
