    Abstract :

    Speech signal denoising is a highly researched topic and here in this paper we discuss denoising using Independent Component analysis and Wavelet transform , Wavelet Thresholding is applied to noise dominated signal and both method of thresholding soft and hard is used . Independent Component analysis is a separation method which is dependent on blind source method. In this paper ICA is discussed and applied for speech denoising. Simulation results indicate that both the proposed method exhibit superior denoising performance but performance of ICA was better compared to Wavelet
