Abstract		This paper presents an ef ort to provide a more efficient speech signal representation, which aims to be incorporated into an automatic speech recognition system. Modified cepstral coefficients, derived from a multiresolution auditory spectrum are proposed. The multiresolution spectrum was obtained using sliding single point discrete Fourier transformations. It is shown that the obtained spectrum values are similar to the results of a nonuniform filtering operation. The presented cepstral features are evaluated by introducing them into a simple phone recognition system.
