Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
204 words
An improvement in a card reading type teaching machine adapted to read an information card having a magnetic stripe for providing normal hearing of one's own voice, comprising, in combination: a transducing means for recording information on the card and reproducing information from the card; card transport means for moving the card from a first position past the transducing means to a second position and returning the card to the first position; a microphone for receiving a person's spoken sounds and producing a microphone output signal; a sound output means for producing an audible signal; an amplifier; switch means movable between a record mode and a playback mode for alternately connecting said amplifier to said microphone and transducing means when in a record mode, for recording the microphone output signal on the magnetic stripe and for connecting the transducing means and amplifier with the sound output means when in the playback mode for audibly reproducing a recorded signal from the magnetic stripe; and an instantaneous feedback means connecting said amplifier with said sound output means by a non-frequency responsive attenuated path whereby the information being recorded is simultaneously transmitted to the sound output means to permit the user to simultaneously hear an undistorted reproduction.

An improvement in a card reading type teaching machine adapted to read an information card having a magnetic stripe for providing normal hearing of one's own voice, comprising, in combination: a transducing means for recording information on the card and reproducing information from the card; card transport means for moving the card from a first position past the transducing means to a second position and returning the card to the first position; a microphone for receiving a person's spoken sounds and producing a microphone output signal; a sound output means for producing an audible signal; an amplifier; switch means movable between a record mode and a playback mode for alternately connecting said amplifier to said microphone and transducing means when in a record mode, for recording the microphone output signal on the magnetic stripe and for connecting the transducing means and amplifier with the sound output means when in the playback mode for audibly reproducing a recorded signal from the magnetic stripe; and an instantaneous feedback means connecting said amplifier with said sound output means by a non-frequency responsive attenuated path whereby the information being recorded is simultaneously transmitted to the sound output means to permit the user to simultaneously hear an undistorted reproduction.
Claim 3
Dependent Claim
37 words
The teaching machine of claim 1 including at least two recording tracks, a first track for carrying a model message and a second track on the information card for recording the information from the sound input means.
Claim 4
Dependent Claim
24 words
The teaching machine of claim 2 including control means for selectively audibly reproducing information from either of said recording tracks on the information card.
Claim 5
Dependent Claim
29 words
The teaching machine of claim 1 wherein the sound output means comprises a headphone set which fits snugly against the head of the user to substantially eliminate environmental noise.
Claim 6
Dependent Claim
37 words
The teaching machine of claim 4 including at least two recording tracks, a first track for carrying a model message and a second track on the information card for recording the information from the sound input means.
Claim 7
Dependent Claim
24 words
The teaching machine of claim 5 including control means for selectively audibly reproducing information from either of said recording tracks on the information card.
Claim 8
Dependent Claim
38 words
The teaching machine of claim 1 wherein the sound output means includes an audio speaker, a set of headphones and a headphone jack switch, said speaker and headphones being alternately connected by said jack switch to said amplifier.
Claim 9
Dependent Claim
33 words
The teaching machine of claim 7 wherein the instantaneous feedback means includes means defining a second attenuated path in the record mode to decrease the signal to the speaker to an inaudible level.
Claim 10
Dependent Claim
176 words
An instantaneous feedback system for an instructional card reader adapted for an informaton card having a first and second recording track thereon comprising, in combination: transducing means for recording and reproducing an instructional model message on said first recording track and for recording and reproducing a student's oral signal onto said second recording track; an amplifier means including switch means connected to said transducing means for reproducing said first track and said second track selectively with either a headphone or a loudspeaker so as to permit the student to hear said instructional message or the student's signal; a microphone connected to said amplifier for receiving the student's signal and providing a microphone output signal to the amplifier for recording by the transducing means on the second track; and an instantaneous feedback means connecting said amplifier means to said headphone or loudspeaker through a non-frequency responsive attenuated path whereby the information being recorded on the second track is simultaneously transmitted to the headphone or loudspeaker to permit the user to hear an undistorted reproduction of his signal.
Claim 11
Dependent Claim
176 words
An instantaneous feedback system for an instructional card reader adapted for an informaton card having a first and second recording track thereon comprising, in combination: transducing means for recording and reproducing an instructional model message on said first recording track and for recording and reproducing a student's oral signal onto said second recording track; an amplifier means including switch means connected to said transducing means for reproducing said first track and said second track selectively with either a headphone or a loudspeaker so as to permit the student to hear said instructional message or the student's signal; a microphone connected to said amplifier for receiving the student's signal and providing a microphone output signal to the amplifier for recording by the transducing means on the second track; and an instantaneous feedback means connecting said amplifier means to said headphone or loudspeaker through a non-frequency responsive attenuated path whereby the information being recorded on the second track is simultaneously transmitted to the headphone or loudspeaker to permit the user to hear an undistorted reproduction of his signal.
Claim 12
Dependent Claim
27 words
The instantaneous feedback system of claim 9 wherein said switch means comprises a headphone jack for selectively and alternatively connecting said headphones or loudspeaker with said amplifier.
Claim 13
Dependent Claim
36 words
The instantaneous feedback system of claim 10 wherein the instantaneous feedback means connecting said loudspeaker to said amplifier includes a second attenuating means for reducing the signal to the loudspeaker to an inaudible level during recording.
