Abstract
A communication system with interchangeable overlays for recording and playing audio data corresponding to graphical and/or textual elements on an overlay wherein the audio data is stored upon the overlay. The communication system with interchangeable overlays includes a communication device having a touch pad integrated within, an overlay removably positionable within the communication unit, and a control unit attached to the overlay. An interface within the control unit allows communication with the communication unit when the overlay is positioned upon the touch pad. The control unit has two main types of recordable data contained within: “structure data” for identifying one or more elements upon the overlay, and “audio data” that corresponds to the elements of the overlay.
