Computerized system and method for evaluating a psychological state based on voice analysis

A voice analyzer processor for processing and implementing a computerized method for performing a harmony analysis of a voice measurement, said voice analyzer is configured to:

• a) receive and record at least one voice measurement from at least one user;
• b) define a sampling rate for each voice measurement;
• c) automatically calculate fast Fourier transform (FFT) spectrum values associated to each voice measurement, based on said sampling rate;
• d) perform plurality of corresponding calculations, thereby said voice analyzer is further configured to:
• i) automatically calculate an entropy value that is characterising said FFT spectrum values, based on probability analysis;
• ii) construct harmonic frequency based on peak values of said FFT spectrum values;
• construct dis-harmonic frequency based on frequency peak values of said FFT spectrum values;
• and, automatically calculate variability of said harmonic or dis-harmonic frequency averaged values;
• or automatically calculate the ratio between said harmonic frequency averaged value and said dis-harmonic frequency values;
• iii) identify correspondences between said frequency peak values of said FFT spectrum values or their average value, to the golden proportion, in a deviation of up to 20% in reference to the golden proportion;
• e) separately normalize the results of each said corresponding calculations into one parameter ranging from 0 to 1, relating to each voice measurement;
• and
• f) unify said parameters, each refers to each voice measurement, into one final parameter;
• wherein said final parameter is designed to characterize a harmony degree in said voice measurements of said user, thereby reflecting user's physiological state.
