This document provides a user manual for flite, a small, fast run-time speech synthesis engine.
This manual is nowhere near complete.
Flite offers text to speech synthesis in a small and efficient binary. It is designed for embedded systems like PDAs as well large server installation which must serve synthesis to many ports. Flite is part of the suite of free speech synthesis tools which include Edinburgh University's Festival Speech Synthesis System http://www.festvox.org/festival and Carnegie Mellon University's FestVox project http://festvox.org, which provides tools, scripts, and documentation for building new synthetic voices.
Flite is written in ANSI C, and is designed to be portable to almost any platform, including very small hardware.
Flite is really just a synthesis library that can be linked into other programs, it includes two simple voices with the distribution, an old diphone voice and anb example limited domain voice which uses the newer unit selection techniques we have been developing. Neither of these voices would be considered production voices but server as examples, new voices will be released as they are developed.
The latest versions, comments, new voices etc for Flite are available from its home page which may be found at
