|  Re: First program for the V364
There's no bug. The T6712 speech chip is not phoneme based and as such can only work with fixed vocabularies. That's part of the reason why the Magic Voice has never become popular. Think of the T6721 and the PARCOR method as a way of voice data compression, much like today's MP3, only in 8 kHz telephone quality.
When you specify an unknown word (ie. not in the fixed vocabulary), you get this "ILLEGAL QUANTITY" error.
What this "program" really does is that it provides new speech data (starting at memory location $6000) that you can use either from BASIC (after issuing the command VOC(address)) or machine code. Custom words (or in this case: complete sentences) are always numbered from 1024. Of course one could as well write directly to the Toshiba chip, then you do not have to deal with these issues.
