"BUT, I'm still curious what the difference is between the old SC-01, SSI
(which I think is really an SC-02), and these SP-0250 and 0256 chips"
SC-01's are analog speech synthesizers. you set pitch and specifiy parameters
to generate speech parts (eee aaa sss...) and string them together.
SP250/256's and TI 5220's are similar, but are more 'dsp' ish in that
you pass them digital filter coefficents and sound generator parameters
in a compressed stream. The 256 has a lookup table to generate phonemes
similar to the SC01. SC-02's were second generation Votrax parts.
Did anyone ever turn up the data sheets for SC-01's or O2's?
