localService property

bool get 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.

Implementation

external bool get localService;
