This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The default
read-only property of the SpeechSynthesisVoice
interface returns a Boolean
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.
var amIDefault = speechSynthesisVoiceInstance.default;
A Boolean
.
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'; } option.setAttribute('data-lang', voices[i].lang); option.setAttribute('data-name', voices[i].name); voiceSelect.appendChild(option); }
