Iterative refinement of amplitude and phase in single-channel speech enhancement

Pejman Mowlaee, Mario Kaoru Watanabe, Rahim Saeidi

While the state-of-the-art speech enhancement methods are focused on the modification of the noisy spectral amplitude, our recent findings demonstrate positive impact of incorporating the speech phase spectrum in speech enhancement. In this show and tell proposal, we demonstrate the recent progress towards utilizing the phase information in closed-loop iterative manner leading to the joint enhancement of amplitude and phase spectra. In this show and tell, we provide a demo where a recorded speech corrupted with noise is enhanced by an iterative refinement of amplitude and phase. The improvement in speech enhancement in various signal-to-noise ratios is justified by improved perceived speech quality as well as not degrading the speech intelligibility performance.
