The two demo programs that did text to speech for you (one was more sophisticated BASIC program) from the Workbench 1.x disks still work on all KS2/KS3.x Amigas.
I never understood why Commodore didn't spent a few extra pennies in maximising what was STILL an impressive party piece of the Amiga ie perfectly acceptable text to speech in hardware/software (PAULA/Libraries) when MS/IBM/APPLE were all parading their overpriced or rubbish freebie versions like prize cocks even though they were a decade late to that particular party

What I would like to know is were there any more sophisticated versions ever produced in PD or for sale commercially?
When I get a chance I am going to do a crazy video of singing Amigas lol
