Re: FreeTTS with Gnome-Speech Question

[Janina Sajka <janina afb net>]

Hi, Bill:

The person who told us was T.V. Raman. I know, because I was with you when he said that.

I subsequently tried Raman's Emacspeak fix on ViaVoice and it did improve, but did not fix, things. It brought the ViaVoice speed down enough to be
intelligible. But, it was still running around 2X speed.

Raman is supposed to send me a fix for my .emacs. I'll forward that and his lisp code inside the Emacspeak files, if I can find it.

Of course, maybe we should just ask him!
