The SPO256 is a Speech Synthesizer chip used in many hardware Speech Synthesizers of the 8bit era. The SP0256 contains a Voice Generator, a small microprocessor, and a built-in ROM which contains 16Kbit (2Kbyte) of program code.
A number of different versions of the SP0256 exist. The most common is the SP0256-AL2, where -AL2 means that the built-in ROM contains preprogrammed english allophones(all 59 phonemes of the English language plus 5 pauses of different lengths).
