SpeechRecognitionError

The SpeechRecognitionError interface of the Web Speech API represents error messages from the recognition service.

Properties

SpeechRecognitionError also inherits properties from its parent interface, Event.

SpeechRecognitionError.error Read only

Returns the type of error raised.

SpeechRecognitionError.message Read only

Returns a message describing the error in more detail.

Examples

var recognition = new SpeechRecognition();

recognition.onerror = function(event) {
  console.log('Speech recognition error detected: ' + event.error);
  console.log('Additional information: ' + event.message);
}

Specifications

Browser compatibility

Firefox OS permissions

To use speech recognition in an app, you need to specify the following permissions in your manifest:

"permissions": {
  "audio-capture" : {
    "description" : "Audio capture"
  },
  "speech-recognition" : {
    "description" : "Speech recognition"
  }
}

You also need a privileged app, so you need to include this as well:

  "type": "privileged"
