On IOS there is "tts-progress" event which you can subscribe to, for android though there is no equivalent event emitted by this library. It should be extended to support https://developer.android.com/reference/android/speech/tts/UtteranceProgressListener.html#onRangeStart(java.lang.String, int, int, int)
