You might check at Radio Shack...I recall that they had a chip that decoded the tone signals and put out the results on several lines that could probably be used as input to a parallel I/O port. They also had a phoneme-oriented voice generator that could be used to put out the voice. Of course, you would also have to add the line-interface circuitry...I beleive Dallas Semiconductor has a full range of chips that handle this type of thing. In fact, I seem to recall that their latest catalog had a 300/1200 baud modem chip that had all the circuitry to go from the computer bus to the phone wall-socket, and included a voice-generator...not sure whether it also had a tone-decoder, but I wouldn't be surprised...If you're interested, drop me a note...I'll check next time I look at the catalog.
