{{APIRef("Web Speech API")}}

The voice property of the {{domxref("SpeechSynthesisUtterance")}} interface gets and sets the voice that will be used to speak the utterance.

This should be set to one of the {{domxref("SpeechSynthesisVoice")}} objects returned by {{domxref("SpeechSynthesis.getVoices()")}}. 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 {{domxref("SpeechSynthesisUtterance.lang","lang")}} setting.

Value

A {{domxref("SpeechSynthesisVoice")}} object.

Examples

js
const synth = window.speechSynthesis;

const inputForm = document.querySelector("form");
const inputTxt = document.querySelector("input");
const voiceSelect = document.querySelector("select");

const voices = synth.getVoices();

// …

inputForm.onsubmit = (event) => {
  event.preventDefault();

  const utterThis = new SpeechSynthesisUtterance(inputTxt.value);
  const selectedOption =
    voiceSelect.selectedOptions[0].getAttribute("data-name");
  for (const voice of voices) {
    if (voice.name === selectedOption) {
      utterThis.voice = voice;
    }
  }
  synth.speak(utterThis);
  inputTxt.blur();
};
