Is there a way to get German text to speech in festival?

Searching for info about German text to speech, I came across a "Dialog-based Human-Technology Interaction by Coordinated Analysis and Generation of Multiple Modalities", as well as this page , which I can't really parse. I mean, it *mentions* festival several times... Hm... I've loaded voices and languages into festival using apt-get, for Finnish, Spanish, Czech, and Russian . I've also loaded voices into festival by wget-ing some files and renaming them in accordance with festival's directory structure. So... is there a way to use either of those two methods to enable German text to speech on my machine?
