SpeechSynthesisUtterance.onerror

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

The onerror property of the SpeechSynthesisUtterance interface represents an event handler that will run when an error occurs that prevents the utterance from being succesfully spoken (when the error event fires.)

Syntax

speechSynthesisUtteranceInstance.onerror = function() { ... };

Examples

var synth = window.speechSynthesis;

var inputForm = document.querySelector('form');
var inputTxt = document.querySelector('input');
var voiceSelect = document.querySelector('select');

var voices = synth.getVoices();

  ...

inputForm.onsubmit = function(event) {
  event.preventDefault();

  var utterThis = new SpeechSynthesisUtterance(inputTxt.value);
  var selectedOption = voiceSelect.selectedOptions[0].getAttribute('data-name');
  for(i = 0; i < voices.length ; i++) {
    if(voices[i].name === selectedOption) {
      utterThis.voice = voices[i];
    }
  }

  synth.speak(utterThis);

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

  inputTxt.blur();
}
