Enhancement of speech in non stationary noise environments has been a major research topic due to its wide range of applications, e.g., in hearing aids. This paper proposes a method for performing dual channel speech enhancement. The proposed method involves the estimation of speech and noise short term predictor (STP) parameters using a codebook based approach, when we have access to binaural noisy signals. The estimated STP parameters are subsequently used for enhancement in a dual channel scenario. Objective measures indicate, that the proposed method is able to improve the speech intelligibility and quality.
