Sound chips

They may very well still sell it. I built a parallel port speech sythethiser
from one and plans from one of the then popular computer or electronics
magazines. I may even have it still in one the boxes that I packed way back
and haven't since opened. It had the same phonetics system as some of the
SoundBlaster chips and had the same monotone speak that the old Dr. SBaitso
and that Hawkings' synth have. Nonetheless it was cool to hear speech from
my 8088 then.

Back in the early '80's they sold that speech chip in a blister pack. I
the crux was getting the 3.12 MHz (I remember that only because getting one
such a PITA) crystal, though, for which the device was specified, and which
to come from somewhere else at the time. Aside from having to translate the
timing intervals, I think a color-burst crystal would probably work with
device, though. A 10-12% increase in pitch wouldn't make much difference as
as intellibility is concerned.
