Abstract:- -Presently Speech Communication becomes active area in signal processing. Many approaches are developed previously for enhancing of speech. Perceptual speech enhancement methods perform better than the non perceptual methods, but most of them still return annoying residual musical noise. When noise above the noise masking threshold is filtered then noise below the noise masking threshold can become audible if its maskers are filtered is the main reason for residual noise. This affect the performance of perceptual speech enhancement method that process audible noise only. To overcome this drawback here proposed a new speech enhancement technique by modifying the Perceptual Wiener filter. The simulation results shows that the performance of this method which is improved when compared to other perceptual speech enhancement methods.
