Remarks

This is called when the TTS service is about to speak the specified range of the utterance with the given utteranceId.

This method is called when the audio is expected to start playing on the speaker. Note that this is different from #onAudioAvailable which is called as soon as the audio is generated.

This information can be used, for example, to highlight ranges of the text while it is spoken.

Only called if the engine supplies timing information by calling SynthesisCallback#rangeStart(int, int, int).
