Abstract :

Speech is basic way of communication between the people but generally it is contaminated by unwanted background adaptive noise. To improve the quality of speech signal speech enhancement techniques are used, like speech enhancement using wavelet based transform, super soft thresholding, adaptive least mean square, basic spectral subtraction method, discrete cosine transform, singular value decomposition, etc. The noisy signal and clean speech signal is measured with the help of peak signal to noise ratio (PSNR) and Minimum mean square error (MMSE). The proposed work helps in choosing the speech enhancement method along with their relative merits & demerits.
