To help people learn to read, it would be helpful to have the ability to click on individual words and hear them read. (Rather than just a whole phrase.)
You should be able to tweak Aeneas to do this. I might be wrong but you should be able to use the space marker as a “phrase ending character” in the Aeneas wizard. This way, each phrase would be just a word. You may have to insert a special character like the zero width space character. Then you could use this character as a phrase boundary.
