Subband Approach for Automatic Speaker Recognition: Optimal Division of the Frequency Domain

This paper presents a new method for automatic speaker recognition. The principle is to split the whole spectral domain into partial frequency subbands on which recognizers are independently applied and then recombined to yield a global recognition decision. In this article, we particularly discuss the selection of the most critical subbands for the speaker recognition task and the choice of an optimal division of the frequency domain.
