Parts count!?!?  Exactly what are you using to drive this system.  I've
found two essentially equivalent phoneme or allonym based speech synthesis
systems for the C64 computer in my work.  The first of these take the 
software approach.  It requires a microprocessor, some simple kind of 
sound chip (I know the generally available GI or Yamaha ships work fine),
and about 32K-64K or ROM.  The program called "SAM" for the C64 does exactly
this.  A hardware alternative is available in the speech cartridge made by
Steve Currah.  This device contains a GI speech chip, a PLA, and I believe
an 8K ROM.  The pure software solution ends up costing about the same as
the hardware assisted solution.  The GI phonemes replace the soft coded
phonemes.  You might end up with 1-1/2 extra chips in the hardware
solution, but you also end up with much more processor time available for
things other than talking.
