Example of SpeechRecognition API usage

speech-recognition.js

let recognition = new window.SpeechRecognition();
recognition.interimResults = true;
recognition.addEventListener('result', e => {
  const transcript = Array.from(e.results)
    .map(result => result[0])
    .map(result => result.transcript)
    .join('');
  
  if (e.results[0].isFinal) {
    // this is the final version, feel free to do whatever you need with transcript/text
  }
});

recognition.addEventListener('end', e => {
  // recognition finished, you can stop recording here
});

// call this one to start recording
recognition.start();

// call this to stop recording
recognition.stop();
