During the transition to wideband speech telephony, artificial band-width extension (ABE) could help to preserve customer satisfaction by enhancing speech quality in case of narrowband (NB) calls. However , the assessment of speech quality for ABE systems is still an open question. In the literature, instrumental measures are often used to judge the quality(More)
Among different microphone array processing techniques , data-dependent beamforming has been proven to be effective in suppressing ambient noise. When applied for dereverberation, however, the adaptation process results in a biased estimate of the beamformer coefficients leading to strong distortions at the beamformer output. In this paper, we investigate(More)
