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'); 
}
