There is so much more to say about the SP0256. I just made a first cut at restructuring the page to account for the fact that the SP0256 is a family, and not all SP0256s are SP0256-AL2s. The Intellivoice, for example, does not use an SP0256-AL2. It uses an SP0256-012, which has completely different phrases programmed into it. -- Mr z ( talk) 06:40, 22 August 2011 (UTC) reply

Where do the SP0256A and SP0256B (with the "A" and "B") fit in? Are those just revision of the original? Also, I believe there was a companion chip that translated ASCII to the allophone codes that might be worth mentioning if anyone happens to know the name...

Yes, the CTS265A-AL2 does ASCII-allophone conversion. It's an early PIC micro-controller programmed with the National Technical Information Service document "AD/A021 929" text to phoneme rules. Datasheet is in the Archer Semiconductor Reference Guide 1988 (p.77, on archive.org), other manuals on bitsavers in /components/gi/speech/ scruss ( talk) 17:47, 19 June 2022 (UTC) reply
