- Mind that completion of an allophone doesn't mute the voice generator (it'll keep repeating the end of the allophone until receiving a new allophone). To mute the voice generator, output a short pause (eg. PA1) after your last allophone.
- The "Funny" timings are from the SP0256-AL2 data sheet (these values are totally wrong).
- The "Actual" timings are calculated from the pitch/repeat values in the AL2 ROM (these values should be 100% correct).
Other Allophone/Word Sets
For curiosity, below are some other SP0256-xx variants (none of the known CPC devices are using that variants though).

This chip is used in the "Intellivoice" expansion module for Mattel's Intellivision.

There isn't much known about the SPB640 FIFO, as far as I understand, it does have three functions: It can hold up to 64 word/allophone numbers (to be injected to A1..A8 pins of the SP0256), it can hold opcodes/parameters (to be injected to SER IN pin of the SP0256), and it includes a general purpose I/O port.

SP0256-019 (or rather SP0256B-019) Allophone/Word/Phrase List
This chip is used in "The Voice", an expansion module for the Odyssey 2. The chip contains the following allophones and words:
80h..BFh Allophones (same as 00h..3Fh on SP0256-AL2) C0h "Enemy" C1h "All clear" C2h "Please" C3h "Get off" C4h "Open fire" C5h "Watch out" C6h "Mercy" C7h "Hit it" C8h "You blew it" C9h "Do it again" CAh "Incredible" FAh "U.F.O." FBh "Monster!"
Not sure why bit7 is set in the codes (it should be written like so to the O2 I/O ports, but maybe the bit isn't actually passed to the SP0256 chip)? Additionally, the expansion module contains 3 built-in speech ROMs with sound effects and various words/phrases like "Amazing", "Come on", "Outch", etc. Moreover, Odyssey 2 game cartridges can contain up to 5 external speech ROMs. For details see "Odyssey 2 Technical Specs" from Daniel Boris.
- Distorted SP0256-AL2 allophones as 8bit WAV files - Caution this file contains corrupted AL2 allophones (apparently recorded without issuing a PAUSE after each allophone, so the allophones have wrong length. For example, /A0/ should repeat 8 times, but in the WAV file it accidently repeats 10.5 times) (note: instead of using the physical durations, the length of the recordings seems to be based on the lengths specified in the datasheet, which are totally wrong)
