I haven't had time to work on this at all since v1.0a3 and I'm gonna be away from the bbs for a couple months.

If someone else is interested in continuing development, please feel free to do so. You just need the source to flite and my diffs which are included in the ttsd package. As the thread's been pretty quiet I wouldn't be surprised if nobody did... in which case I'll resume work on it in a few months.
