With the correct software.  Unless you can get hold of this, it would
take a lot of work to try to get the card to operate.

If you are lucky, the software is all in ROM, and can be activated by
using PR#n.

A speech synthesizer.  I remember seeing one (briefly) several years
ago.

Synthesized speech output, probably based on a phoneme system.

Audio output.  I can't tell you whether it is line-level or amplified.

You need the card.  I think I once knew what the electrical interface
was like, but I've forgotten now.  It certainly isn't RS-232/422/423
compatible.
