SpeechSynthesisVoice.voiceURI

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

The voiceURI read-only property of the SpeechSynthesisVoice interface returns the type of URI and location of the speech synthesis service for this voice.

Syntax

var myVoiceURI = speechSynthesisVoiceInstance.voiceURI;

Value

A DOMString representing the URI of the voice. This is a generic URI and can point to local or remote services, e.g. it could be a proprietary system URN or a a URL to a remote service.

Examples

for(i = 0; i < voices.length ; i++) {
  var option = document.createElement('option');
  option.textContent = voices[i].name + ' (' + voices[i].lang + ')';

  if(voices[i].default) {
    option.textContent += ' -- DEFAULT';
  }

  console.log(voices[i].voiceURI);
  // On Mac, this returns URNs, for example 'urn:moz-tts:osx:com.apple.speech.synthesis.voice.daniel'

  option.setAttribute('data-lang', voices[i].lang);
  option.setAttribute('data-name', voices[i].name);
  voiceSelect.appendChild(option);
}
