A Review of Speech Signal Enhancement Techniques

Speech is the most natural and the most effective way of communication between human. During the speech communication, the signals contains some noise so when processing the digital speech signals; speech signal enhancement is very important step. The field speech processing is an applied area of signal processing. The motive of speech enhancement is to enhance the understandability and comprehensibility of speech signal. There are numbers of techniques proposed using which speech signal enhancement is performed. The objective of this paper is to provide an overview of speech enhancement algorithms which are used for enhancement of speech signal.
