SpeechRecognition: result event

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The result event of the Web Speech API is fired when the speech recognition service returns a result — a word or phrase has been positively recognized and this has been communicated back to the app

Bubbles No
Cancelable No
Interface SpeechRecognitionEvent
Event handler property onresult

Examples

This code is excerpted from our Speech color changer example.

You can use the result event in an addEventListener method:

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

recognition.addEventListener('result', function(event) { 
  var color = event.results[0][0].transcript;
  diagnostic.textContent = 'Result received: ' + color + '.';
  bg.style.backgroundColor = color;
});

Or use the onresult event handler property:

recognition.onresult = function(event) {
  var color = event.results[0][0].transcript;
  diagnostic.textContent = 'Result received: ' + color + '.';
  bg.style.backgroundColor = color;
}

  • [1] Speech recognition interfaces are currently prefixed on Chrome, so you'll need to prefix interface names appropriately, e.g. webkitSpeechRecognition; You'll also need to serve your code through a web server for recognition to work.
  • [2] Can be enabled via the media.webspeech.recognition.enable flag in about:config, although note that currently speech recognition won't work on Desktop Firefox — it will be properly exposed soon, once the required internal permissions are sorted out.
