- Abstract
Most dereverberation methods aim to reconstruct the anechoic magnitude spectrogram, given a reverberant signal. Regardless of the method, the dereverberated signal is systematically synthesized with the reverberant phase. This corrupted phase reintroduces reverberation and distorsion in the signal. This is why we intend to also reconstruct the anechoic phase, given a reverberant signal. Before processing speech signals, we propose in this paper a method for estimating the anechoic phase of reverberant chirp signals. Our method presents an accurate estimation of the instantaneous phase and improves objective measures of dereverberation.
