. If not set by the time the utterance is spoken, the voice used will be the most suitable default voice available for the utterance's lang
setting.

var myVoice = speechSynthesisUtteranceInstance.voice; speechSynthesisUtteranceInstance.voice = speechSynthesisVoiceInstance;
Value
A SpeechSynthesisVoice
object.

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) {
