dockstar text to speech

Hi,
I am trying to install basic tools to convert a text file to wav or mp3 sound file.
Easy to do under windows. But I need it under dockstar. I've heard of festival. I tried flite and I got an error about default audio device.
Is there any contribution for this or detailed installation and usage procedure. Any interesting topic would of great value.
What would I need to do it?

thanks.

Finally, I got festival working. Results are not great with poor voices, only english.
keep an eye on this other thead too: http://ubuntuforums.org/showthread.php?t=751169
But thanks anyway.

It's not worth getting an automatic text to speech, under linux, nor windows. Because , you first have to retouch accents, pronunciation defaults, punctuation ...
But windows provide more quality choice and a user-friendly interface.
Produce late quality mp3 story is a better choice.
