On the application of psychoacoustically-motivated dereverberation for recordings taken in the German parliament

Abstract:

In this paper, we discuss the application of speech dereverberation techniques for post-processing of recordings taken in the German parliament. Based on a novel psychoacoustically-motivated dereverberation concept, a significant improvement in terms of the perceived quality is obtained in comparison to a conventional dereverberation approach. Since time-varying changes of the acoustical environment are negligible, all required acoustical parameters such as reverberation time (RT) and direct-to-reverberant-energy ratio (DRR), are determined in an off-line procedure.
