Festival Source Distribution

Version 2.4 Release December 2014

Festival offers a general framework for building speech synthesis systems as well as including examples of various modules. As a whole it offers full text to speech through a number APIs: from shell level, though a Scheme command interpreter, as a C++ library and an Emacs interface. Festival is multi-lingual (currently English (British and American), and Spanish) though English is the most advanced. Other groups release new languages for the system. And full tools and documentation for build new voices are available through Carnegie Mellon's FestVox project (http://festvox.org)

The system is written in C++ and uses the Edinburgh Speech Tools Library for low level architecture and has a Scheme (SIOD) based command interpreter for control. Documentation is given in the FSF texinfo format which can generate, a printed manual, info files and HTML.

Festival is free software. Festival and the speech tools are distributed under an X11-type licence allowing unrestricted commercial and non-commercial use alike.

This distribution includes:

Full English (British and American English) text to speech
Full C++ source for modules, SIOD interpreter, and Scheme library
Lexicon based on CMULEX and OALD (OALD is restricted to non-commercial use only)
Edinburgh Speech Tools, low level C++ library
Full documentation (html, postscript and GNU info format)

Note there are some licence restrictions on the voices themselves. The US English voices have the same restrictions as Festival. The UK lexicon (OALD) is restriction to non-commercial use.

Addition voices are also available.
