Hi,
This page:
http://www.robotprojects.com/voice/voice.htm
Lists the Currah Speech 64 as using a SP0256-AL2, which is a speechsynth
by General Instruments, later Microchip. You give it the number of an
allophone, and it will speak it.
Note that the SP0256-AL2 is a regular SP0256 with a standard set of
allophones integrated in a mask-rom. You may still give it an external
rom though.
