EDIT2: Penguinbait, I just found a more direct way to get audio to work in Festival, when I was poking around init.scm trying to figure out how to change to a different voice. Turns out there's an (undocumented) Audio_Method called esdaudio, so you only need to add one line to festival.scm: Code: (Parameter.set 'Audio_Method 'esdaudio)
(Parameter.set 'Audio_Method 'esdaudio)
