SpeechSynthesisUtterance.onmark

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

The onmark property of the SpeechSynthesisUtterance interface represents an event handler that will run when the spoken utterance reaches a named SSML mark tag (when the mark event fires.)

Syntax

speechSynthesisUtteranceInstance.onmark = 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.onmark = function(event) {
    console.log('A mark was reached: ' + event.name);
  }

  inputTxt.blur();
}
