GNUspeech

FYI. I don't know if this has been formally announced. This project was 
recently donated to GNU, and apparently will become the 'official' speech 
program (and possible speech recognition) program of GNU.  I think the source 
is now on savannah or soon will be. They haven't asked for help in doing any 
porting, but if you would like to help, please let me know.
