An alpha-numeric computer keyboard is designed with a built-in stereo and electronic switching circuitry to enable students (users) to build proper key boarding skills and develop speed in the shortest possible time. Students listen to the recorded instructions on the tape and transcribe groups of letters, words, phrases, sentences, numbers, and symbols/punctuation marks as they are dictated, using the proper finger to strike each key. The dictation is stopped by a signal on the tape and restarted when the student depresses the last key of the segment, making the speed completely natural for each student to build speed while developing skill. This is accomplished by wiring specific keys, for example Space, Period and Enter as momentary switches which are connected to a selection switch for restarting the tape each time the last key of a segment is depressed by the student so that the next item can be heard immediately.
