Noticed both of those effects here too.

I've tried it on a pIII 866, which should really suffice for whatever speech
synthesis needs.  Character-echo is not really usable, since it does speak
chars very "late".

ViaVoice uses the Eloquence engine, which is more or less The Product
for accessibility today.  JAWS for instance uses the same engine to
do its software synthesis.  And even my Nokia Communicator 9210 with the
Talx screen reader uses a Eloquence engine.

I have to agree that Viavoice sounds much better and seems to be faster
to me than dectalk software.

If you figure out what tools to use, and how to do it without having to
use graphical tools, I'd like to know about that too please.
