The Suggestion : there are several 'voice digitizer' programs around which have the user build some external circuitry and connect it to a serial port. Then a program reads the port. I believe that the external circuitry converts the voice into 5 v pulses. This scheme may be modifiable for your use. I have a file called "DIGITIZE.ZIP" on my BBS at 619-549-3927. A friend built the external circuit and it worked. It is cheap with Radio Shack parts.
