1. Apparatus for detecting unconscious general emotions of an individual, the apparatus comprising(a) a vocal source input;
- (b) an analog to digital converter operative to perform a digitization process of an analog audio vocal segment received from the individual via the vocal source input;
(c) a central processing unit (CPU) configured to retrieve digitized data provided by the analog to digital converter and determine a general emotional state of the individual; and
(d) a general emotion reporter, operative to produce an indication of any kind of the general emotions being part of the general emotional state determined by the CPU;
wherein said CPU determines the general emotional state of the individual by calculating a spectrum of a predetermined number of frequencies from a plurality of suitable samples of a portion of the vocal segment, and analyzing the spectrum of the vocal segment to obtain an indication of the individual'"'"'s general emotions according to the digitized data, using at least one of the following;
(a) a most significant frequency of the spectrum;
(ii) a total sum of at least one of lowest analyzed frequencies;
(iii) a total sum of at least one of frequencies in a relatively high bound of the spectrum;
(iv) a total sum of at least one of highest analyzed frequencies; and
(v) a percentage contribution of the most significant frequency to the spectrum.

Abstract
The present invention relates to an apparatus for monitoring emotional states of an individual by using a voice analysis of said individual. The apparatus comprises a voice analyzer operative to input speech specimens, comprising an analog to digital converter operative to perform a digitization process of analog audio vocal segments, and a general emotion reporter, operative to produce an indication of any kind for the monitored general emotions. According to preferred embodiment of the present invention, the speech specimens are provided over the telephone to the voice analyzer and the report of the subject'"'"'s emotional state includes a “love detection” report based on the individual'"'"'s sub-conscious emotional state.

18. A method of detecting unconscious general emotions of an individual, the method comprising:
-
(a) receiving analog vocal data; (b) obtaining digitized data by digitization of an analog audio vocal segment being part of the analog vocal data; (c) based on the digitized data, determining a general emotional state of the individual; and (d) producing an indication of any kind of the general emotions being part of the determined general emotional state; wherein said determining comprises; calculating a spectrum of a predetermined number of frequencies from a plurality of suitable samples of a portion of the digitized data; and analyzing the spectrum of the vocal segment for obtaining an indication of the individual'"'"'s general emotions using at least one of the following; (i) a most significant frequency of the spectrum; (ii) a total sum of at least one of lowest analyzed frequencies; (iii) a total sum of at least one of frequencies in a relatively high bound of the spectrum; (iv) a total sum of at least one of highest analyzed frequencies; and (v) a percentage contribution of the most significant frequency to the spectrum.
