The technology used by festival/flite is different to that used by
ViaVoice, but I get the feeling the general consensus is that the
festival/flite technology offers the promise of more human like voices
than ViaVoice. From what I've been told, creating new voices for
festival is a bit of an art form and this will probably improve as
people get to understand it better. The up side is that you do get use
to the difference and should soon be able to understand festival/flite
voices as easily as the ViaVoice ones.

The poorer quality of flite voices is due to it using 8k samples,
rather than 16k which festival can use. If flite is modified to use
16k voices, its quality will be as good. I beleive I read somewhere
that there were people working on this.

Thats od - I don't get a german sound to the voices at all. Which
voices are you using for festival?

There are two interface versions to festival I know of. One uses a
perl script and can be found at http://espeakf.sourceforge.net and the
other works by modifying emacspeak itself, but I have not tried it
yet. See http://www.pollock-nageoire.net/festival/ for details. 

There is also a java based speech synthesizer called freeTTS, which
does not really have an interface to emacspeak, but it probably
wouldn't be difficult to implement. I have not tried this synthesizer
either and have no idea about its quality. I think the project is also
hosted by sourceforge.
