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();
}
