Zusammenfassung:	A method for recognizing the sex of a voice signal and an apparatus therefor are provided to recognize the sex by differently applying the weighted values which are produced by using the distinctive weight learning according to each degree of an MFCC feature vector, thereby improving the sex recognition performance. A voice signal is inputted(S501). From the inputted voice signal, an MFCC feature vector is extracted(S502). According to each degree of the extracted MFCC feature vector, distinctive weighted values are given(S503). The sex of the inputted signal is recognized by a decision formula to which the distinctive weighted values given according to each of the degrees are applied. Particularly, the sex is distinguished through a value, obtained by multiplying the weighted values with each degree of MFCC feature vector, and a kernel function.
