error (SpeechRecognitionError)

The error event of the Web Speech API SpeechRecognition object is fired when a speech recognition error occurs.

Examples

var recognition = new SpeechRecognition();

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.

Specifications

Browser compatibility

• [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.

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"
