boosting responsiveness of accent pc

Hi all.

Is it just me, or is the accent pc sluggish when used with speakup?
What I mean is the longer the string the accent pc has to speak, the
more of a delay there is before the string is spoken. Here is an
illustration of what I'm talking about.

Say for example you type the string:

"This is a rather longish test sentence."

on a blank line without the quotes. If you then use the numpad-8 key to
read the line with speakup, there is a delay of almost one second
between when the read line key is pressed, and when the accent pc
actually starts to speak the sentence. On the other hand, if I type
the same phrase on a blank line using a doubletalk pc, the doubletalk
pc speaks the phrase immediately when the read line key is pressed.

I suspect, though am not positive, that this is a speakup-specific
issue, since I don't have this delay when using window-eyes or provox
with the accent pc. This behavior holds true for speakup 1.5, and cvs
speakup, so this is not something that was introduced recently. In
fact, I have noticed this issue since I got my accent pc about a year
and a half ago, but didn't comment on it until now, since I couldn't
think of a clear way to describe the problem. 

I do remember that playing with delay_time and jiffy_delta was
suggested on here before to improve synth responsiveness, however, as
I recall, this suggestion was made only if one uses the stock
redhat/fedora kernel, and I am using my own kernel build from the
vanilla kernel.org source tarball.

Any comments would be appreciated. Thanks.

Greg
