SpeechSynthesisVoice.localService
The localService
read-only property of the
SpeechSynthesisVoice
interface returns a boolean value
indicating whether the voice is supplied by a local speech synthesizer service
(true
), or a remote speech synthesizer service (false
.)
This property is provided to allow differentiation in the case that some voice options are provided by a remote service; it is possible that remote voices might have extra latency, bandwidth or cost associated with them, so such distinction may be useful.
Value
A boolean value.
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].localService);
option.setAttribute('data-lang', voices[i].lang);
option.setAttribute('data-name', voices[i].name);
voiceSelect.appendChild(option);
}
