SpeechSynthesisVoice: default property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2018.

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

js
for (const voice of voices) {
  const option = document.createElement("option");
  option.textContent = `${voice.name} (${voice.lang})`;

  if (voice.default) {
    option.textContent += " — DEFAULT";
  }

  option.setAttribute("data-lang", voice.lang);
  option.setAttribute("data-name", voice.name);
  voiceSelect.appendChild(option);
}
