Speech enhancement using cross-correlation compensated multi-band Wiener filter combined with constrained perceptual weighting filter

Abstract

An improved Wiener filtering method for reducing background noise added to speech in colored noise environments like car engine is proposed in this paper. This implementation uses the crosscorrelartion between the speech and noise signals. The noise signal does not affect the speech signal uniformly over the whole spectrum. A nonlinear multi-band Bark scale… (More)
