The SP0256 was GI's formant synth version of the chip. They simply took the
SP0250 added an internal ROM of LPC recorded formant phrases for 56(?)
different parts of speech. Then instead of accessing full phrases, you
accessed formants and strung them together to create phrases.

The SP0256 was the chip Radio Shack sold for a while back in the '80s.

Maybe this is what Larry was referring to.
