eSpeak generates a espeakEVENT_SENTENCE event for the next word after
end-of-sentence (i.e. full-stop, question mark, exclamation mark, or
paragraph).  eSpeak reads and processes text a phrase at a time.  So at
that point it doesn't know how long the sentence will be (it's only
read the phrase).

You could look for the next full-stop, question mark, etc.

eSpeak processes text in a similar way.

It can be useful to highlight words as they are spoken, but I'm not
sure about highlighting sentences or phrases.

You could look for the end of a phrase by looking for the next comma,
semi-colon, etc. and highlight the text up to that.  eSpeak generates
an espeakEVENT_END event at the end of a phrase, so at that point you
can look for the end of the next phrase and highlight that.
