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