ABSTRACT:
An electronic teaching apparatus which utilizes interchangeable flexible overlays with printed pictorial representations in conjunction with a programmable keyboard. An integrated circuit speech synthesizer is utilized to verbally ask an operator to select a particular pictorial representation or to verbally identify a pictorial representation selected by the operator. Upon the failure of the operator to correctly select a particular pictorial representation, the verbal request can be repeated in conjunction with a verbal description of some attribute of the desired pictorial presentation. Each of the interchangeable overlays is coded to allow control circuitry to select a proper sequence of words for a given overlay.
