Verbara.Sdk.VoiceAi.TurnDetection

ML-based turn detection for the Verbara.Sdk VoiceAi pipeline using the Pipecat smart-turn-v3 ONNX model. Detects semantic end-of-turn boundaries — not just silence — for more natural conversational turn-taking.

Installation

dotnet add package Verbara.Sdk.VoiceAi.TurnDetection

Note: This package bundles the smart-turn-v3.2-cpu.onnx model as an embedded resource. CPU inference works on all platforms. GPU acceleration (CUDA / DirectML) requires the matching ONNX Runtime provider package.

Quick Start

Replace the default SilenceTurnDetector with the smart ML-based detector by calling AddSmartTurnDetection in your DI setup:

services.AddVoiceAiPipeline<MyHandler>();
services.AddSmartTurnDetection(opts =>
{
    opts.TurnConfidenceThreshold = 0.5f;   // probability threshold (0.0–1.0)
    opts.SilenceTriggerDuration  = TimeSpan.FromMilliseconds(200);
    opts.BargInVoiceThreshold    = TimeSpan.FromMilliseconds(200);
    opts.ExecutionProvider       = ExecutionProvider.Cpu;
    opts.IntraOpThreads          = 1;
});

AddSmartTurnDetection removes any previously registered ITurnDetector and registers SmartTurnDetector in its place.

Configuration

Property	Type	Default	Description
`TurnConfidenceThreshold`	`float`	`0.5`	Minimum model probability to classify a pause as end-of-turn
`SilenceThresholdDb`	`double`	`-40.0`	RMS energy threshold (dBFS) for silence detection
`SilenceTriggerDuration`	`TimeSpan`	`200ms`	Silence duration after speech before running the model
`BargInVoiceThreshold`	`TimeSpan`	`200ms`	Voice duration during TTS playback to trigger barge-in
`ExecutionProvider`	`ExecutionProvider`	`Cpu`	ONNX Runtime execution provider
`IntraOpThreads`	`int`	`1`	Number of intra-op threads for ONNX Runtime
