Patent ID: 8321209

Claim:
A method of generating a voice identification in a frequency domain comprising: a processor transforming one or more periods of a voice signal from a time domain to said frequency domain; setting an amplitude of a first harmonic to a first amplitude and adjusting each amplitude of one or more other harmonics to maintain relative gain to said first harmonic; setting a frequency of said first harmonic of said transformed voice signal to a first frequency and adjusting each frequency of one or more other harmonics to maintain harmonic series relative to said first harmonic; filtering said transformed voice signal, including removing one or more frequency components that are above a threshold harmonic, the filtered transformed voice signal comprising one or more remaining harmonics; digitizing the amplitude of each of said one or more remaining harmonics into a first number of bits; digitizing the number of said one or more remaining harmonics into a second number of bits; and, concatenating said first number of bits and said second number of bits to form said voice identification.
