SpeechSynthesisVoice.default

The default read-only property of the SpeechSynthesisVoice interface returns a boolean value indicating whether the voice is the default voice for the current app (true), or not (false.)

Note: For some devices, it might be the default voice for the voice's language. The spec is not very clear on which it should be, so some implementations may differ.

Value

A boolean value.

Examples

for (let i = 0; i < voices.length ; i++) {
  const option = document.createElement('option');
  option.textContent = `${voices[i].name} (${voices[i].lang})`;

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

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