It has been shown that the Iterative Weiner Filtering (IWF) requires both intra-frame and inter-frame constraints to ensure that the enhanced speech spectra possess natural characteristics of speech. One automated way to apply the intra-frame constraints is Codebook Constrained Wiener Filtering (CCWF). In the present work, we propose a new method of imposing the inter-frame constraints based on Markov modeling of speech segments. We will show that the proposed method improves both Average segmental log-likelihood ratio and Average segmental SNR of the enhanced speech even at SNRs below 0dB.
