Abstract
Abstract An electronic speech therapy teaching apparatus for use by a speech therapist includes a silent timer with an associated electronic digital display, an adjustable aural speech rate device, an automatic calculator for computing a student's percentage of correct responses, an electronic display of the accumulation of total and correct responses, and controls to select and operate the various features of the apparatus. The silent timer selectively counts up or down, informing the operator when counting down, through an audio/visual alarm, when a predetermined time period has expired. The adjustable aural speech rate device produces tones at a rate appropriate for the speech student. Manually controlled switches enable the operator to register and display the number of correct and total responses during the evaluation procedure. An automatic computer calculates the percentage of a student's correct responses as they are registered by the operator.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
202 words
Apparatus for recording the performance of a student who is responding to a test environment including a first counter recording a quantity of "correct" signals, a second counter recording the quantity of "correct" and "incorrect" signals, the "correct" and "incorrect" signals being generated by an operator in response to a student's answer, and further including a quantity display for selectively displaying a quantity of "correct" signals from the first counter or the quantity of "correct" and "incorrect" signals from the second counter, the improvement comprising: first circuit means responsive to the quantity of "correct" and "incorrect" signals of the second counter and generating a signal varying in frequency with the recorded quantity, second circuit means responsive to the quantity of "correct" signals in the first counter and generating a signal varying in frequency with the recorded quantity, third circuit means responsive to the signals varying in frequency of said first and second circuit means to generate a percentage signal varying with the percentage of "correct" signals generated for the recorded quantity of "correct" and "incorrect" signals, and percentage display means responsive to the percentage signal for indicating the percentage of "correct" signals generated for the recorded quantity of "correct" and "incorrect" signals.
Claim 2
Dependent Claim
202 words
Apparatus for recording the performance of a student who is responding to a test environment including a first counter recording a quantity of "correct" signals, a second counter recording the quantity of "correct" and "incorrect" signals, the "correct" and "incorrect" signals being generated by an operator in response to a student's answer, and further including a quantity display for selectively displaying a quantity of "correct" signals from the first counter or the quantity of "correct" and "incorrect" signals from the second counter, the improvement comprising: first circuit means responsive to the quantity of "correct" and "incorrect" signals of the second counter and generating a signal varying in frequency with the recorded quantity, second circuit means responsive to the quantity of "correct" signals in the first counter and generating a signal varying in frequency with the recorded quantity, third circuit means responsive to the signals varying in frequency of said first and second circuit means to generate a percentage signal varying with the percentage of "correct" signals generated for the recorded quantity of "correct" and "incorrect" signals, and percentage display means responsive to the percentage signal for indicating the percentage of "correct" signals generated for the recorded quantity of "correct" and "incorrect" signals.
Claim 3
Dependent Claim
54 words
Apparatus for recording the performance of a student as set forth in claim 1 wherein said third circuit means includes: latch means responsive to the frequency signal of said second circuit means and connected to the second counter and said percentage display means for transferring thereto a signal representing the percentage of "correct" signals.
Claim 4
Dependent Claim
52 words
Apparatus for recording the performance of a student as set forth in claim 1 wherein said first circuit means includes a programmable decimal counter responsive to a frequency input and to the quantity of "correct" and "incorrect" signals of the second counter for generating the frequency signal of said first circuit means.
Claim 5
Dependent Claim
51 words
Apparatus for recording the performance of a student as set forth in claim 3 wherein said second circuit means includes a programmable decimal counter responsive to a frequency input and to the quantity of "correct" signals recorded in the first counter for generating the frequency signal of said second circuit means.
Claim 6
Dependent Claim
58 words
Apparatus for recording the performance of a student as set forth in claim 1 including a third counter also recording the quantity of "correct" and "incorrect" signals and further including accumulator display means connected to the third counter for indicating the accumulated quantity of "correct" and "incorrect" signals generated by an operator in response to a student's answer.
