Although Festival may have more hardware requirements than other TTS systems, it's in my experience perfectly usable unless your computer is really old or it doesn't have enough RAM to store voices you use (together with applications you run, of course). IIRC, my six years old PC with 256 MB RAM ran Festival with two languages, Emacs, X, etc. fine. Nevertheless, applications shouldn't assume a TTS can perform just anything they decide to ask for. Common mistake is feeding the Festival SayText function with a long text and waiting for the resulting sound. Festival should be asked to synthesize the text in chunks instead (festival-freebsoft-utils provides means for doing this easily) as it does in the tts_file function. The only real performance problems with Festival I've ever met are: - Festival used to be slow when echoing typed characters. This can be solved easily by caching the synthesized characters (this is what Speech Dispatcher does). - The default utterance chunking mechanism in Festival doesn't cope well with wild input, such as a long text without any punctuation characters or a complicated short text containing a lot of "strange" characters. The utterance chunking frontend in festival-freebsoft-utils deals with most such situations (again, this is what Speech Dispatcher uses). So these problems are easily solvable and nobody needs to be afraid of Festival. :-) Actually Festival with its high quality output, nice features, extensibility, several free voices and support of several languages should satisfy needs of many users.
