Below is a french do it yourself project for connecting a SP0256 speech chip to a printer port, using Data, Strobe=ALD, and Busy=Status.

It isn't actually a CPC project (for the CPC one would need to replace LPRINT by PRINT #8), aside from that, it should be compatible with the CPC printer port (the CPC's GNDed D7 printer bit is no problem, since allophone numbers are only 6bit wide).

No idea what the 74374 latch is intended for, the printer port output should be latched anyways, so it seems to be totally useless.
