Noise impact assessment on the accuracy of the determination of speaker?s gender by using method of the cumulant coefficients

A new method of classification of a speaker´s gender based on cumulant coefficients is proposed. The effect of an additive noise and measurement error of classification signs on accuracy of classification is analyzed. The expediency of construction of an adaptive system of classification operating with considering of masking of a speech signal by noise is shown. Comparison of the proposed method of classification of the speaker´s gender to competing methods shows that the proposed method provides better classification accuracy, resistant to the effects of noise interference and much simpler for technical implementation.
