SileroVAD

Defined in: src/core/vad/SileroVAD.ts:137

Local Silero voice-activity-detection engine.

Remarks

Stateful across frames — call reset between listening sessions so one session’s trailing state does not bias the next.

Example

const vad = new SileroVAD({ modelUrl: '/models/silero_vad_v5.onnx' });
await vad.initialize();

const probability = await vad.process(frame); // Float32Array(512) @ 16 kHz
if (probability > 0.5) console.log('speech!');
