How can I make speechUtterance API utter?

26 views Asked by At

When I type in something in the text area element and then click on the read button nothing is being uttered. The console doesn't throw any error and I can't identify where I've gone wrong either. I went on the "SpeechUtterance" MDN documentation and as far as I can tell I've followed all the right steps. Help please!

const read = document.getElementById("read");
const pause = document.getElementById("pause");
const stop = document.getElementById("stop");
const speed = document.getElementById("speed");
const text = document.getElementById("text");


read.addEventListener("click", () => {
  readText(text.value)
});

pause.addEventListener("click", () => {
  pauseText();
});


function readText(dummy) {
  var utterThis = new SpeechSynthesisUtterance(dummy);
  if(speechSynthesis.speaking && speechSynthesis.paused) {
    return speechSynthesis.resume()
  }

  if(speechSynthesis.speaking) return;

  console.log(utterThis)
  console.log(speechSynthesis)


  utterThis.text = dummy;
  utterThis.rate = speed.value
  text.disabled = true;
  speechSynthesis.speak(utterThis)
  utterThis.addEventListener("end", () => {
    text.disabled = false
  })
}

function pauseText() {
  if(speechSynthesis.speaking)  speechSynthesis.pause();
}
body {
  background-color: purple;
}


textarea {
  margin-top: 50px;
  margin: auto;
}

textarea:focus {
  background: green;

}

.container {
  display: flex;
  justify-content: center;
