Real-Time Voice Activity Detection for Node.JS

This is a fork of @ricky0123/vad which adds RealTimeVAD by building on top of NonRealTimeVAD provided.

Quick Start

const vad = /** import */;

const options = {
  sampleRate: 16000, // Sample rate of input audio
  minBufferDuration: 1, // minimum audio buffer to store 
  maxBufferDuration: 5, // maximum audio buffer to store
  overlapDuration: 0.1,  // how much of the previous buffer exists in the new buffer
  silenceThreshold: 0.5, // threshold for ignoring pauses in speech
};

const rtvad = new vad.RealTimeVAD(/** options */);

rtvad.init();

rtvad.on("start", ({ start }) => {
  // speech segment start
});

rtvad.on("data", ({ audio, start, end}) => {
  // speech segment data
  // start & end here are provided by @ricky0123/vad, this is NOT the same as emitted start & end
});

rtvad.on("end", ({ end }) => {
  // speech segment end
});
