Noise reduction of speech signals is a key challenge problem in speech enhancement, speech recognition and speech communication applications, etc. It has attracted a considerable amount of research attention over past several decades. The most widely used method is optimal linear filtering method, which achieves clean speech estimate by passing the noise observation through an optimal filter or transformation. Most common problem in speech processing is the effect of interference noise in speech signals, Interference noise masks of the speech signal and reduces its Intelligibility. It is necessary to remove the noise from the speech signals to get the clear understanding of the information that the speech signal contains.
