The C64 MagicVoice manual is at http://project64.c64.org/hw/magicvoice.txt. It contains explanation of the BASIC commands, a list of known words and ML programming information. Note that the C364 implementation is said to have more words than the C64.

The C64 MV uses a pretty strange interface to the Toshiba chip, with a
6525 IO chip that talks to the Toshiba through a PLA (plus a 4bit wide,
16bit deep shift register). This must all be integrated in that single
28 pin chip that the 364 has, and probably it is a different implementation than in the C64 MV.
