Abstract
A commercial, two deck, stereo tape system, FIGS. 2 and 3, by means of the system control and switching logic module of FIG. 4 and the manual controls of FIG. 5, is adapted to provide an adjustable, interactive audio training system. A three position switch 503 permits an operator to select from three modes of system operation, namely, normal tape mode, master tape mode and training mode. When the system is in the normal tape mode, the switches of FIG. 3 are in full control. The system can be used exactly the same way as the original two deck stereo tape system. When the system is in the master tape mode, the system control and switching logic module of FIG. 4, in response to signals from manual controls of FIG. 5, permits an instructor to prepare 'Master' tapes which may comprise: lecture material as a preamble to a training exercise; one or more series of 'cues' to which a trainee is to respond; and discretely coded control signals. When the system is in the training mode, the control module, in response to control signals read from a master tape and to trainee voice activity, generates strings of control signals for the tape module of FIG. 2 to automatically sequence presentation of the lesson material without disconcerting demands on a trainee.
