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.
ValueA boolean value.
Examplesfor (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 += " â DEFAULT";
}
console.log(voices[i].localService);
option.setAttribute("data-lang", voices[i].lang);
option.setAttribute("data-name", voices[i].name);
voiceSelect.appendChild(option);
}
