Note (General): In this research, we proposed a two-stage binaural speech enhancement with Wiener filter (TS-BASE/WF) based on the equalization-cancellation (EC) model. In the proposed TS-BASE/WF, the interfering signal is first estimated by equalizing and cancelling the target signal based on the EC model, and a time-variant Wiener filter is then applied to enhance the target signal given the noisy mixture signals. Main advantages of the proposed TS-BASE/WF are: (1) effective in dealing with non-stationary multiple-source interfering signals; (2) successful in preserving the perceptual impression of acoustic scenes. Experimental results in various spatial configurations confirm that the TS-BASE/WF outperforms the traditional binaural speech enhancement algorithms in both speech enhancement and sound localization.
