FIELD: computer technology.
SUBSTANCE: invention relates to the field of computer technology for speech analysis. The effect is achieved due to the fact that the input speech signal is converted using analog-to-digital conversion to a digital representation, divided into time sections - frames, each frame is filtered in a given frequency range by a set of N digital filters in the time domain, while the total bandwidth which is equal to the width of the specified frequency range, and the amplitude-frequency response of each filter is similar to that of the Mel-filter, the filtering results are averaged over the number of frames and used to evaluate the difference measure with the standard.
EFFECT: increasing the probability of correct speaker authentication.
