Parameters

parameters
VoiceDSPParametersRequired

Types

NoiseSuppressionParameters

Extends: Hush.NoiseSuppressionParameters

Hush.NoiseSuppressionParameters based. Can be passed as Agentic.VoiceDSPParameters.noiseSuppressionParameters to Agentic.createVoiceDSP.

TurnDetectorParameters

Extends: Pipecat.TurnDetectorParameters

Pipecat.TurnDetectorParameters based. Can be passed as Agentic.VoiceDSPParameters.turnDetectorParameters to Agentic.createVoiceDSP.

stopSecs
number

optional

Optional. Mirrors Pipecat SmartTurnParams.stop_secs parameter. If the turn analyzer classifies the turn as incomplete, silence must continue for this many seconds before the turn is finalized. The default value is 3.0.

Inherited fields

maxDurationSecs
number

optional, inherited from Pipecat.TurnDetectorParameters

Optional. Maximum segment duration in seconds. The default value is 8.

preSpeechMs
number

optional, inherited from Pipecat.TurnDetectorParameters

Optional. Milliseconds of audio to include before speech starts. The default value is 0.

privacy
boolean

_optional, inherited from WebSocketBasedClientParameters

Optional. Whether to enable the privacy functionality.

If privacy is enabled, the logging for the WebSocket connection is disabled.

NOTE: the default value is false.

statistics
boolean

_optional, inherited from WebSocketBasedClientParameters

Optional. Enables statistics functionality.

threshold
number

optional, inherited from Pipecat.TurnDetectorParameters

Optional. The probability threshold above which we detect the end of the turn (in the range [0.0, 1.0]). The default value is 0.5.

trace
boolean

_optional, inherited from WebSocketBasedClientParameters

Optional. Whether to enable the tracing functionality.

If tracing is enabled, a URL to the trace file appears in the ‘websocket.created’ message. The file contains all sent and received WebSocket messages in the plain text format. The file is uploaded to the S3 storage.

NOTE: enable this only for diagnostic purposes. You can provide the trace file to our support team to help investigating issues.

VADParameters

Extends: Silero.VADParameters

Silero.VADParameters forwarded to the bundled Agentic.VoiceDSP connector (server-side VAD). Can be passed as Agentic.VoiceDSPParameters.vadParameters to Agentic.createVoiceDSP.

Inherited fields

minSilenceDurationMs
number

optional, inherited from Silero.VADParameters

Optional. The duration of silence (in milliseconds) to wait for each speech segment before separating it. The default value is 300.

privacy
boolean

_optional, inherited from WebSocketBasedClientParameters

Optional. Whether to enable the privacy functionality.

If privacy is enabled, the logging for the WebSocket connection is disabled.

NOTE: the default value is false.

speechPadMs
number

optional, inherited from Silero.VADParameters

Optional. The padding to add to speech segments to avoid aggressive cutting. The default value is 0.

statistics
boolean

_optional, inherited from WebSocketBasedClientParameters

Optional. Enables statistics functionality.

threshold
number

optional, inherited from Silero.VADParameters

Optional. The probability threshold above which we detect speech. The default value is 0.5.

trace
boolean

_optional, inherited from WebSocketBasedClientParameters

Optional. Whether to enable the tracing functionality.

If tracing is enabled, a URL to the trace file appears in the ‘websocket.created’ message. The file contains all sent and received WebSocket messages in the plain text format. The file is uploaded to the S3 storage.

NOTE: enable this only for diagnostic purposes. You can provide the trace file to our support team to help investigating issues.

VoiceDSPParameters

Extends: _VoiceAIClientParameters

Agentic.VoiceDSP parameters. Can be passed as arguments to the Agentic.createVoiceDSP method.

asr
ASR

optional

Optional. ASR instance used internally for transcription-based start strategies; the latest transcript snapshot is included on Agentic.VoiceDSPEvents.TurnStopped. Live transcription should be handled via ASREvents on the scenario ASR instance.

asrGraceTimeout
number

optional

Optional. ASR grace period in seconds after Agentic.VoiceDSPEvents.TurnInferenceTriggered. When Agentic.VoiceDSPParameters.asr is configured, Agentic.VoiceDSPEvents.TurnStopped waits up to this duration for a final transcript; a final transcript ends the wait immediately. Default 0.3 - shorter than typical ASR final latency, so Agentic.VoiceDSPEvents.TurnStopped does not wait for ASR final by default. Start LLM inference on Agentic.VoiceDSPEvents.TurnInferenceTriggered. When the timer expires, Agentic.VoiceDSPEvents.TurnStopped uses the latest snapshot (including interim text).

noiseSuppressionParameters
NoiseSuppressionParameters

optional

Optional. Noise suppression configuration forwarded to the bundled voice DSP connector (server-side processing). NOTE: if the parameters are NOT provided, the voice DSP connector will NOT use the noise suppression.

startStrategies
VoiceDSPStrategies.Start[]

optional

Optional. Strategies that determine when a user’s turn starts. Multiple strategies can be provided; the first one to trigger signals the start. Use Agentic.VoiceDSPStrategies factories (for example Agentic.VoiceDSPStrategies.createVADStart).

stopStrategies
VoiceDSPStrategies.Stop[]

optional

Optional. Strategies that determine when a user’s turn ends. Use Agentic.VoiceDSPStrategies factories (for example Agentic.VoiceDSPStrategies.createTurnDetectorStop). If Agentic.VoiceDSPStrategies.TurnDetectorStop is configured, it is authoritative; Agentic.VoiceDSPStrategies.SpeechTimeoutStop does not pre-empt it. One turn always finalizes with a single strategy. NOTE: If no stop strategies are provided, Agentic.VoiceDSPStrategies.createTurnDetectorStop is used as the default. Omit Agentic.VoiceDSPStrategies.TurnDetectorStop to disable ML Predict (for tests or ASR-only stop logic); Agentic.VoiceDSPEvents.TurnInferenceTriggered and Agentic.VoiceDSPEvents.TurnStopped then never report strategy ‘turn_detector’.

turnDetectorParameters
TurnDetectorParameters

optional

Optional. Turn detector configuration forwarded to the bundled voice DSP connector (server-side processing).

userTurnIdleTimeout
number

optional

Optional. User idle timeout in seconds (mirrors Pipecat UserIdleController.user_idle_timeout). After Agentic.VoiceDSP.signalAssistantTurnEnded, if the user remains inactive for this duration, Agentic.VoiceDSPEvents.TurnIdle is emitted. 0 disables idle detection. The default value is 0.

userTurnStopTimeout
number

optional

Optional. Pipecat user_turn_stop_timeout (seconds). Counts silence while a user turn is active; the timer resets on new speech and on ASR updates. If no stop strategy finalizes the turn within this silence, Agentic.VoiceDSPEvents.TurnStopTimeout is emitted with reason controller_timeout, then Agentic.VoiceDSPEvents.TurnStopped. strategy on Agentic.VoiceDSPEvents.TurnInferenceTriggered and Agentic.VoiceDSPEvents.TurnStopped is the pending stop strategy, or the configured fallback if none is pending (never ‘turn_detector’ unless Agentic.VoiceDSPStrategies.TurnDetectorStop is configured). Default 5.0. Set 0 to disable.

vadParameters
VADParameters

optional

Optional. VAD configuration forwarded to the bundled voice DSP connector (server-side processing).

Inherited fields

onWebSocketClose
(event: _WebSocketCloseEvent) => void

_optional, inherited from VoiceAIClientParameters

Optional. A callback function that is called when the WebSocket connection is closed.

privacy
boolean

_optional, inherited from WebSocketBasedClientParameters

Optional. Whether to enable the privacy functionality.

If privacy is enabled, the logging for the WebSocket connection is disabled.

NOTE: the default value is false.

statistics
boolean

_optional, inherited from WebSocketBasedClientParameters

Optional. Enables statistics functionality.

trace
boolean

_optional, inherited from WebSocketBasedClientParameters

Optional. Whether to enable the tracing functionality.

If tracing is enabled, a URL to the trace file appears in the ‘websocket.created’ message. The file contains all sent and received WebSocket messages in the plain text format. The file is uploaded to the S3 storage.

NOTE: enable this only for diagnostic purposes. You can provide the trace file to our support team to help investigating issues.
