11. The method as defined in claim 1 , wherein the at least one feature parameter is one of spectral centroid (SC), spectral spread (SS), zero crossing rate (ZCR), duration fast Fourier transformation (FFT) coefficients, jitter, and fundamental frequency (F 0 ); when the at least one feature parameter is plural in number, each of the feature parameters is one of SC, SS, ZCR, FFT coefficients, jitter, and FO and the feature parameters are different from each other.
13. The method as defined in claim 11 , wherein SC, SS, ZCR, duration, FFT coefficients, and jitter are adopted for age recognition; F 0 and FFT coefficients are adopted for gender recognition.
