SpeechSynthesis.speak()
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
 The speak() method of the SpeechSynthesis interface adds an utterance to the utterance queue; it will be spoken when any other utterances queued before it have been spoken. 
Syntax
speechSynthesisInstance.speak(utterance);
Returns
Void.
Parameters
- utterance
-  A SpeechSynthesisUtteranceobject.
Examples
 This snippet is excerpted from our Speech synthesiser demo. When a form containing the text we want to speak is submitted, we (amongst other things) create a new utterance containing this text, then speak it by passing it into speak() as a parameter. 
var synth = window.speechSynthesis; ... 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); inputTxt.blur(); }
