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

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); }
