Abstract

Electronic apparatus is disclosed which is usable to determine the fluency of a person'"'"'s speech. This apparatus may monitor a dialogue directly, may be connected to a telephone to monitor a dialogue, or may be connected to be responsive to a recording of the dialogue. The apparatus determines the number of hesitation pauses of joint silence of both persons bounded by speech uttered by the subject which pauses are in excess of a time interval in the order of one second of time. The apparatus gives an indication, either visible or audible, when the number of such pauses exceeds a presettable limit per unit of time. The apparatus may be used by the medical profession to determine a subject'"'"'s proneness to clinical coronary atherosclerosis where the rate of such hesitation pauses is in excess of a presettable value. It may also be used by disc jockeys, sales personnel or the like.

Claims

1. The method of diagnosis of proneness to clinical coronary atherosclerosis in a human subject, comprising the steps of;

having the subject utter oral speech,

obtaining from said speech a determination of the hesitation pauses of absence of vocal sounds within the speech uttered by the subject which pauses are in excess of a given time interval in the order of one second of time,

determining the number of such pauses in a period of time of speech of the subject,

and indicating the subject'"'"'s greater proneness to the development of clinical coronary atherosclerosis where the rate of such pauses is in excess of a value in the order of two pauses per minute.

2. The method as set forth in claim 1, including timing the hesitation pauses of the subject,

discarding the pauses which are of shorter duration than said given time interval,

and counting those pauses which are of longer duration than said given time interval.

3. The method as set forth in claim 1, including counting the number of hesitation pauses of the speech of the subject which are of longer duration than said given time interval which counting is for a given period of time to determine the rate of such pauses.

4. The method as set forth in claim 1, wherein said step of indicating includes a visible indicator.

5. The method as set forth in claim 1, wherein said step of indicating includes illuminating a red light upon the rate of such pauses exceeding a value of substantially two pauses per minute.

6. The method as set forth in claim 1, wherein the subject is uttering oral speech as part of a dialogue with another person.

7. The method as set forth in claim 6, wherein the hesitation pauses are pauses of joint silence of both parties and bounded by speech of the subject.

8. The method as set forth in claim 6, wherein the other person asks a series of questions,

and the step of determining the number of hesitation pauses is determining the pauses of joint silence of both parties and bounded by the answers given by the subject to the questions propounded by the other person.
