In this paper we explore speech dereverberation techniques whose principle is the recovery of the envelope modulations of the original (anechoic) speech [3],[4]. Based on our previous experience with such kind of processing for additive noise reduction applications, we apply a data designed filter-bank technique [2] to the reverberant speech. Comparing our results with other works we discuss the effectiveness and limitations of this type of approaches.
