Mark,

I don't recall the exact part # off the top of my head, but it's a
small, 16 pin, 8 bit  microcontroller with the formant speech processing
hardware built in.  I believe it's a member of the TSP50C0x/1x family.
It's an LPC system, and the idea was to pull large volumes of speech out
of an external ROM for the stand alone mode.  Barney also "speaks" with
streaming voice data from it's RF link (5 kbs).  I'm partial to this
family of chips when a design requires speech, due to the fact that they
are also g.p. processors that can be used to control other I/O
requirements in your designs.

This web page has the essentials from TI:

I hope this helps.

Cheers,

Chuck Mauro
