Abstract

This article presents a study of the effect of acoustic reverberation on speech intelligibility. This evaluation includes the use of the classics ideal binary masks IdBM and IRM and the blind non-ideal mask BRM. Three objective measures fwSegSNR, CSII, and STOI in addition to the quality measure SegSNR are considered in the experiments. The results show that reverberation impacts speech intelligibility and that binary masks are capable of improving the degraded intelligibility. Moreover, it is demonstrated that BRM increased the intelligibility of reverberated signals in different scenarios.
