VADOptions class
Per-call options. Field vocabulary follows LiveKit/Silero naming.

Properties
- activationThreshold ↔ double
-
Unset = keep the loaded detector's calibrated value. Same normalized
0,1scale as VADConfiguration.activation_threshold.getter/setter pair - hashCode → int
-
Calculates a hash code based on the contents of the protobuf.
no setterinherited
- info_ → BuilderInfo
-
no setter
- isFrozen → bool
-
Returns
trueif this message is marked read-only. Otherwisefalse.no setterinherited - maxSpeechDurationMs ↔ int
-
Force-split a monologue longer than this. Unset = unbounded.
getter/setter pair
- minSilenceDurationMs ↔ int
-
Hangover: continuous silence this long ends the turn. This is the
primary latency dial. Defaulted for TURN-TAKING (OpenAI
silence_duration_ms = 500), not for ASR segmentation (Silero = 100).
getter/setter pair
- minSpeechDurationMs ↔ int
-
Debounce: speech shorter than this is discarded (coughs, clicks, taps).
getter/setter pair
- prefixPaddingMs ↔ int
-
Pre-roll kept before SPEECH_STARTED so the first phoneme survives.
Included in the emitted segment's audio_start_ms (OpenAI semantics).
getter/setter pair
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- sampleRate ↔ int
-
Capture rate of the audio fed to the detector, for the whole session.
Nothing resamples: a mismatch yields wrong segment durations. Bound is
identical to VADConfiguration.sample_rate and the commons validator —
if the project narrows to Silero/LiveKit's {8000,16000}, change all
three together.
getter/setter pair
- unknownFields → UnknownFieldSet
-
no setterinherited
