- Reimplentation of the core parts of the Festival architecture

- Support for compiling FestVox voices into Flite voices.
- Thread safe
- Scalable voice size with all data const so it can be in
- Target architectures, ipaq (Linux/WinCE), Palm OS (treo)
Flite is in basically written and is in its first stages of
testing before release, as free software. A small diphone voice
based on the CMU KAL voice is included. along with a sample
limited domain talking clock.
