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