A New Approach for Speech Enhancement Based On Eigenvalue Spectral Subtraction

In this paper , a phase space reconstruction – based method is proposed for speech enhancement . The method embeds the noisy signal in to a high dimensional reconstructed phase space and user Spectral Subtraction idea. The advantages of the proposed method are fast performance , high SNR and good MOS .In order to evaluate the proposed method ten signals of TLMIT database mixed with the white additive Gaussian noise and then the method was implemented . The efficiency of the proposed method was evaluated by using qualitative and quantitative criteria.
