Abstract

A system and method monitor the emotional content of human voice signals after the signals have been compressed by standard telecommunication equipment. By analyzing voice signals after compression and decompression, less information is processed, saving power and reducing the amount of equipment used. During conversation, a user of the disclosed methodology may obtain information in visual format regarding the emotional state of the other party. The user may then assess the veracity, composure, and stress level of the other party. The user may also view the emotional content of his own transmitted speech.

Claims

1. A method of detecting the emotional content in compressed voice signals comprising the steps of:

(a) receiving compressed voice signal;

(b) uncompressing the voice signal;

(c) from the uncompressed signal, measuring the fundamental frequency of the user for variations in frequency;

(d) assigning an emotional state to the measured frequency; and

(e) reporting the measured emotional state.

2. The method of claim 1, including the measurement of tambour.

3. The method of claim 1, including the measurement of volume.

4. The method of claim 1, including the measurement of amplitude.

5. The method of claim 1, including the use of lossly compression.

6. The method of claim 5, including the reconstruction of lost data after compression.

7. A device for detecting the emotional content in compressed voice signals comprising:

(a) means of receiving an uncompressed voice signal;

(b) means of compressing a voice signal;

(c) means of analyzing the emotional content of the compressed voice signal;

(d) means of assigning an emotional state to the analyzed compressed voice signal; and

(e) means of reporting the assigned emotional state.

8. The device of claim 7 wherein a vocoder is used to measure the emotional state of the compressed voice signal.

9. The device of claim 7 with means to use lossly compression.

10. The device of claim 9 with means to restore lost data after lossly compression.

11. The device of claim 10 that includes a mobile hand set.

12. The device of claim 111 that includes a screen to display the emotional content of the received speech.

13. The device of claim 12 that includes means to measure the emotional content of the user'"'"'s speech.

14. The device of claim 13 that includes means to display to the user the emotional content of the speech being transmitted.

15. The device of claim 14 that includes means to remove the emotional content of transmitted speech.
