SpeechSynthesisVoice.localService
This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The localService
read-only property of the SpeechSynthesisVoice
interface returns a Boolean
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.
Syntax
var amILocal = speechSynthesisVoiceInstance.localService;
Value
A Boolean
.
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); }
