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

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.

Syntax

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

Value

A DOMString representing 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];
    }
  }
  console.log(utterThis.text);
  synth.speak(utterThis);
  inputTxt.blur();
}
