SpeechSynthesisUtterance.onend

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

The onend property of the SpeechSynthesisUtterance interface represents an event handler that will run when the utterance has finished being spoken (when the end event fires.)

Syntax

speechSynthesisUtteranceInstance.onend = 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.onend = function(event) {
    console.log('Utterance has finished being spoken after ' + event.elapsedTime + ' seconds.');
  }

  inputTxt.blur();
}
