Speech enhancement using iterative Wiener filtering has been shown to require interframe and intraframe constraints in all-pole parameter estimation. In this correspondence, we show that a clean speech VQ codebook is more effective in providing intraframe constraints and, hence, better convergence of the iterative filtering scheme. Satisfactory speech enhancement results are obtained with a small codehook of 128, and the algorithm is effective for both white noise and pink noise up to 0 dB SNR.
