Abstract
Warped analysis-synthesis filter-banks with Bark-scaled frequency bands are used for speech enhancement systems to improve the subjective speech quality. In this contribution, an alternative warped filter(-bank) structure is proposed which has a significantly lower signal delay and algorithmic complexity. The warped moving-average low delay filter allows to decrease the signal delay in a simple and flexible manner. The warped auto-regressive low delay filter has minimum phase property and can achieve a delay of only a few samples. The application to speech enhancement shows that a similar subjective quality for the enhanced speech can be achieved as by means of a warped analysis-synthesis filter-bank.
