@ariontalk/plugin-silero-vad

Silero VAD barge-in plugin for ArionTalk — AI-powered voice activity detection.

Install

npm install @ariontalk/plugin-silero-vad

@ariontalk/core is a peer dependency.

Usage

import { SileroVadDetector } from '@ariontalk/plugin-silero-vad';

// Use with the widget
widget.bargeInPlugins = [
  {
    id: 'silero-vad',
    label: 'Smart VAD',
    create: () => new SileroVadDetector({ onnxWASMBasePath: '/' }),
  },
];

Options

| Option | Default | Description | |--------|---------|-------------| | positiveSpeechThreshold | 0.7 | Detection sensitivity (0–1) | | negativeSpeechThreshold | 0.55 | Silence threshold (0–1) | | minSpeechMs | 500 | Minimum speech duration in ms | | redemptionMs | 1400 | Grace period for pauses in ms | | baseAssetPath | "./" | Path to VAD model assets | | onnxWASMBasePath | "./" | Path to ONNX WASM runtime files |

How it works

Silero VAD uses a lightweight ONNX neural network to detect speech with higher accuracy and fewer false positives than energy-based detection. Dependencies are lazy-loaded — the model is only fetched when a session starts.
