Voice recognition with the Apple-Psych system

Use of the IntroVoice I voice recognition board with the Apple-Psych system is described. The device augments the EF ROM, keyboard ROM, and keyboard encoder chip in Apple II series computers and provides speaker-dependent recognition of up to 80 words. IntroVoice II, an upgrade, can recognize up to 160 words. Since the operation of IntroVoice is software-transparent, the Apple-Psych system recognizes the board’s output as console (keyboard) input, making it useful as a response collection device. The keyboard continues to operate normally, in parallel with voice recognition. Problems and solutions for response recognition and timing are discussed, and illustrative experimental data are presented.
