IIRC if was partly hardware - possibly just the phonomes blown onto a chip
- but you could look in one of the amiga emulator packages.

You can do fun things with formant filters (vowel peaks - theres a dial
that goes from A to EE) and envelope sequencers.

If there isn't a formant filter for LADSPA allready available someone
should make one - the tables of co-efficients are available online.
