Could that do the voice recognition functions? The Apple-CAT II sounds like a conventional modem.

I think the unique thing about this IBM sound cards is that it had a programmable DSP which made it much more flexible.

Yes, my recollection is that it could recognize voice on the line. Besides that:

- It had a four-voice synthesizer, so it could play music / synthesize voices, etc over the line.

- It had a handset input, I think w/digitizer, so it could be used as a voice distorter.

- It supported Bell 202 1200 bps half-duplex to another Cat II.

- It could control a tape recorder, so it could be used as an answering machine.

- It could control home appliances via BSR X-10.

- It had RS-232 support, so it could be used as a serial printer controller.

It was not a conventional modem.
