These chips (the SPO256-AL2 and the CTS256A-AL2) seem really hard to find
these days, but I've found a supplier of them if anyone is interested. A
U.S. company called SMC Electronics, based in Brockton, MA, has the
SPO256-AL2 for $US5.00 and the CTS256A-AL2 for $US7.50 (both include
specification and application sheets).
SMC Electronics web page is http://personal.tmlp.com/SMCONE/
The chips are listed on http://personal.tmlp.com/SMCONE/IC.HTM

Curiously
enough, the text-to-speech capabilities of this machine sound
awfully close to the speech-sound pack I have for my CoCo's... methinks
it's based on the same chipset, as they're roughly the same era.
Could well be. There were a pair of chips from GI - one was the SPO256
which was a speech synthesiser chip, and the other was the CTS256 which
was a PIC7000 (TMS7000-a-like), I think, programmed with the
text-to-speech algorithm. The Speech-sound pack for the Coco used a
microcontroller (I forget which) with much the same algorithm, but also
with commands to control an AY3-891x sound chip.
