ABSTRACT:
A multichannel sound recording and playback device is described, which comprises a integrated circuit memory unit for storing messages, a microphone for feeding messages to the memory unit, a speaker for transmitting messages from the memory unit, message actuation devices uniquely associated with the different messages, and control circuitry (logic gates) for enabling and/or disenabling the memory unit and microphone, and for causing transmission of a given message when that message's actuation device is actuated. A preferred form of memory unit is an electrically erasable read-only analog memory IC chip, which permits very low power consumption (less than 100 microamps) during standby. A method for improving language and communication skills of a child is also described, using the device of the invention with pictures affixed to the message actuation devices.
