The spectral effects of vocal tract length (VTL) differences are one reason for the lower recognition rate of today's speaker-independent automatic speech recognition (ASR) systems compared to speakerdependent ones. By using certain types of filter banks the VTL-related effects can be described by a translation in subband-index space. In this paper, nonlinear translation-invariant transformations that originally have been proposed in the field of pattern recognition are investigated for their applica… Show more
