praat with espeakedit plug-in (windows version)

I compiled it with MinGW. It will be useful for eSpeak developers. However, this no longer works for the latest eSpeak version because eSpeak uses praat_5xxx now. praat_5xxx seems not able to be built on Windows because it uses ALSA library.

eGuideDog::Festival (Perl module) - Wrapper of common functions of Festival TTS

Festival is a famous open source TTS engine, which is written in Scheme (a variant of Lisp). To do some controlling with the voice, for example, speaking some words in a stronger voice or speaking it faster, Scheme language should be used. I've already wrote a Perl module for common Festival functions.
