A. K. Verma, A. R. Verma, Manoj Kumar . 2-D Speech Enhancement based on Curvelet Transform using Different Window Functions. International Journal of Computer Applications. 81, 13 ( November 2013), 1-4. DOI=10.5120/14069-2276
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.
