A spectral conversion approach to the iterative Wiener filter for speech enhancement

Abstract

The iterative Wiener filter (IWF) for speech enhancement in additive noise is an effective and simple algorithm to implement. One of its main disadvantages is the lack of proper criteria for convergence, which has been shown to introduce severe degradation to the estimated clean signal. Here, an improvement of the IWF algorithm is proposed, when additional… (More)
