Properties

audioFilePath ↔ String
Absolute path to an audio file. Required when audio_source is AUDIO_SOURCE_FILE; ignored for MICROPHONE / CALLBACK sources.
getter/setter pair
audioSource ↔ AudioSource
getter/setter pair
bargeInThresholdMs ↔ int
getter/setter pair
chunkMs ↔ int
getter/setter pair
emitPartials ↔ bool
Emit partial transcripts as UserSaidEvent{is_final=false}.
getter/setter pair
emitThoughts ↔ bool
Emit thought tokens (qwen3, deepseek-r1) separately from answer tokens.
getter/setter pair
enableBargeIn ↔ bool
Barge-in behavior.
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 true if this message is marked read-only. Otherwise false.
no setterinherited
llmModelId ↔ String
Model identifiers — resolved against the model registry.
getter/setter pair
maxContextTokens ↔ int
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
sampleRateHz ↔ int
Audio configuration.
getter/setter pair
sttModelId ↔ String
getter/setter pair
systemPrompt ↔ String
LLM behavior.
getter/setter pair
temperature ↔ double
getter/setter pair
ttsModelId ↔ String
getter/setter pair
ttsVoiceId ↔ String
pass3-syn-025/030: explicit TTS voice id for multi-voice TTS engines (Piper, eSpeak-NG, Sherpa-ONNX-TTS multi-voice). When unset, callers fall back to using tts_model_id as the voice id — correct for single-voice engines, wrong for multi-voice. Aligns the caller-facing VoiceAgentConfig with the commons-facing RAVoiceAgentComposeConfig (voice_agent_service.proto:214) which already exposes tts_voice_id.
getter/setter pair
typeKind ↔ SolutionType
Optional explicit solution-kind tag. Redundant with the SolutionConfig oneof arm; provided so callers that pass this message standalone (or log it) can read a single discriminator. Defaults to UNSPECIFIED.
getter/setter pair
unknownFields → UnknownFieldSet
no setterinherited
vadModelId ↔ String
getter/setter pair
