ABSTRACT:
An improvement is provided in an audio visual teaching device which is particularly suitable for teaching the proper and correct pronunciation of words, phrases, etc. The device employs a card handling mechanism for moving an information card across a record/playback transducing head. A dual track magnetic stripe on the card carries information on one track indicating the correct pronunciation of a particular word or group of words which the student can hear through a speaker or preferably a set of headphones. Additionally, the device includes a microphone and record portion so that the student can practice speaking a word which then is simultaneously recorded on a second track on the magnetic stripe so that the student may replay the second track and listen to his own pronunciation and compare it to the model on the first track. The improvement comprises an instantaneous feedback system to the headphones so that the students may simultaneously hear through the headphones an audible signal that is being recorded on the information card when pronouncing a word. The instantaneous feedback system permits objective and simultaneous hearing of the student's own words.
