Answer 1

In case anyone is still looking into this, I found a really nice C++ predictive text library called Presage. It seems to do a good job based on the demo but I'm having a lot of trouble trying to integrate it as a library (see my question here).

Let me know if anyone has any ideas, very interested in getting this working!
