SpeechRecognitionError.message

The message read-only property of the SpeechRecognitionError interface returns a message describing the error in more detail.

Syntax

var myErrorMsg = event.message;

Value

A DOMString containing more details about the error that was raised. Note that the spec does not define the exact wording of these messages — this is up to the implementors to decide upon.

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"
