The text property of the SpeechSynthesisUtterance interface gets and sets the text that will be synthesised when the utterance is spoken.

The text may be provided as plain text, or a well-formed SSML document. The SSML tags will be stripped away by devices that don't support SSML.

var myText = speechSynthesisUtteranceInstance.text;
speechSynthesisUtteranceInstance.text = 'Hello I am speaking';

Value

A DOMString represenitng the text to the synthesised. The maximum length of the text that can be spoken in each utterance is 32,767 characters.

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];
