This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The error event of the Web Speech API SpeechRecognition object is fired when a speech recognition error occurs.
| Bubbles | No |
| Cancelable | No |
| Target objects | SpeechRecognition |
| Interface | SpeechRecognitionError |
| Event handler property | onerror |
Examples
You can use the error event in an addEventListener method:
var recognition = new webkitSpeechRecognition() || new SpeechRecognition();
recognition.addEventListener('error', function(event) {
console.log('Speech recognition error detected: ' + event.error');
});
Or use the onerror event handler property:
recognition.onerror = function(event) {
console.log('Speech recognition error detected: ' + event.error');
}
Inheritance
The error event implements the SpeechRecognitionError interface, which inherits from Event — it has available the properties and methods defined on both these interfaces.

- [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.enableflag 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.
