Description

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.

Here are slides about Flite from a recent talk given by AWB slides.ps slides.pdf
