I'm using kernel 2.4.26 under Slackware 9.1 if that helps.  Just to verify
that it is indeed the Dectalk, I turned off speech and used Brltty only to
read several emails, while repeating the same loop on another console of
comparing the date with the system clock.  It stayed stable.  As soon as I
started up the Dectalk speaking again, it started wondering again.  When I
started typing this message, it was within a few milliseconds, and is now
over 4 seconds off.  Since you were using it under Redhat, I'm wondering
if the Dectalk driver is tuned for Redhat's faster clock rate?  I recall
when Redhat 8 came out, they tweaked a value having to do with the clock
speed of the kernel or something, and a lot of people had to adjust
jiffy_delta and delay_time in Speakup to compensate because it caused
their synthesizers to be choppy.  I'm wondering if adjusting those values
might help?  My jiffy_delta is 50, and my delay_time is 500 now, which are
default values.
