Flite (festival-lite) is a small, fast run-time synthesis engine
developed at CMU and primarily designed for small embedded
machines and/or large servers. Flite is designed as an
alternative synthesis engine to Festival for voices built
using the FestVox suite of
voice building tools.
Flite 1.4-release is now released as source. Flite offers:
- Completely in C (no C++ or Scheme) for portability, size and
speed
- Reimplentation of the core parts of the Festival architecture
(HRG) allowing close compabilility between voices built for each
system.
- Support for compiling FestVox voices into Flite voices.
- Thread safe
- Scalable voice size with all data const so it can be in
ROM
- Target architectures, ipaq (Linux/WinCE), Palm OS (treo)
and smaller
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.
