Brad Stewart, Covox
Brad Stewart was the co-founder and chief designer of Covox, the company that created Covox VoiceMaster. VoiceMaster was speech digitizer and voice recognition hardware for the Commodore 64, Atari 8-bit, and Apple II computers. Covox's own demonstration audio tape describes it well, although the demo tape that I found doesn't mention the Atari.
This interview took place on May 21, 2020.
