Currently, that is not implemented in this Cordova plugin. The functionality is there in the underlying target APIs for Android and iOS. I haven't looked into Windows Phone.
For this to work in TTS, it would have to expose or encapsulate the proper callbacks/delegates.
In iOS, it looks like we'd probably be making use of AVSpeechSynthesizerDelegate and speechSynthesizer(_:willSpeakRangeOfSpeechString:utterance:)

In Android, it looks like we'd be dealing with SynthesisCallback.rangeStart and UtteranceProgressListener.onRangeStart
https://developer.android.com/reference/android/speech/tts/SynthesisCallback.html#rangeStart(int, int, int)
https://developer.android.com/reference/android/speech/tts/UtteranceProgressListener.html#onRangeStart(java.lang.String, int, int, int)
It would be nice to have this functionality on a project I may be working on. If so, when the time comes, if it hasn't been added by someone, yet, I may give it a try.
I successfully integrated tts plugin. I would like to know if somehow I can highlight currently spoken words on my front-end. In other words if it could simultaneously speak and output as in text form what is currently being spoken.
Thanks
