A Level-Dependent Auditory Filter-Bank for Speech Recognition in Reverberant Environments

Abstract

Distortions due to reverberation have detrimental effect on the performance of automatic speech recognition (ASR). In this work, an auditory filter-bank based feature is presented to improve the ASR in reverberant conditions. The proposed technique is based on the gammachirp filter bank which provides level dependent frequency response to emulate mechanisms… (More)
