SpeechRecognition: soundstart event

The soundstart event of the Web Speech API is fired when any sound — recognisable speech or not — has been detected.

Examples

You can use the soundstart event in an addEventListener method:

var recognition = new webkitSpeechRecognition() || new SpeechRecognition();

recognition.addEventListener('soundstart', function() { 
  console.log('Some sound is being received');
});

Or use the onsoundstart event handler property:

recognition.onsoundstart = function() { 
  console.log('Some sound is being received'); 
}
