This is an experimental technologyCheck 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();
}
