A clean speech VQ codebook has been shown to be effective in providing intraframe constraints and hence better convergence of the iterative Wiener filtering scheme for single channel speech enhancement. Here we present an extension of the single channel CCIWF scheme to binaural speech input by incorporating a speech distortion weighted multi-channel Wiener filter. The new algorithm shows considerable improvement over single channel CCIWF in each channel, in a diffuse noise field environment, in terms of a posteriori SNR and speech intelligibility measure. Next, considering a moving speech source, a good tracking performance is seen, up to a certain resolution.
