Flite is a small, fast run-time synthesis library suitable for embedded systems and servers. Flite is designed as an alternative run-time synthesis platform for Festival in applications where speed and size are important. Voices built using the FestVox process may be compiled into efficient representations that can be linked against Flite to produce complete text-to-speech synthesizers. The Flite library is much faster and much smaller than the equivalent Festival system. This paper describes the motivation and the basic structure of the library, and gives figures of its size and speed. Some intended enhancements are also discussed.
