Abstract
In modern telecommunication systems the presence of noise in background degrades the overall intelligibility and quality of the speech signal. The problem of enhancing speech signals and reducing acoustic noise from the noisy environment using adaptive filtering algorithms with incorporation of blind source separation approach has drawn a particular attention in the recent past. In this paper a dual channel double backward distributive weighted adaptive filtering algorithm is proposed for speech quality enhancement. The proposed method has been evaluated using the objective measures such as Perceptual Evaluation of Speech Quality (PESQ) and Short Time Objective Intelligibility (STOI) in different noise setup and the results achieved indicate that this is a better method for speech quality improvement.
