A Novel Robust Speech Feature Based on the Mellin Transform and Speaker Normalizatuin

Abstract

A novel robust feature of speech signal has been proposed by us in [1]. The new feature is the modified Mellin transform of the log-spectra of speech signal and is short for MMTLS. Due to the scale invariance property of the modified Mellin transform, the MMTLS is insensitive to the vocal tract length of different speakers. Thus it is more appropriate for… (More)
