error

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The error event of the Web Speech API SpeechSynthesisUtterance object is fired when an error occurs that prevents the utterance from being succesfully spoken.

Bubbles No
Cancelable No
Target objects SpeechSynthesisUtterance
Interface SpeechSynthesisErrorEvent

Examples

utterThis.onerror = function(event) {
  console.log('An error has occurred with the speech synthesis: ' + event.error);
}

Inheritance

The error event implements the SpeechSynthesisErrorEvent interface, which extends the SpeechSynthesisEvent interface, which in turn inherits from Event. It therefore has available the properties and methods defined on all these interfaces.
