Abstract

In this paper, an improved method based on Curvelet Transform using different window functions is presented for the speech enhancement. The window function is used for pre-processing of speech signals. In this method, instead of using two-dimensional (2-D) discrete Fourier Transform, Curvelet transform is employed with spectral magnitude subtraction method.
