The area of speech recognition is one of the interesting field in speech signal processing. Achieving accuracy and robustness is a very difficult constraint to various environmental factors. Progressive work and reviews in the speech recognition application has been adopted using fuzzy, as one of the technique to improve the recognition accuracies. This review paper reviews the various concepts of fuzzy technique and its applications to speech signal processing area. Since the nature of speech

... ignal is vague, it does not pocess uniformity at all time intervals. To deal with this vagueness and uncertainties, many researchers have suggested fuzzy is one of the better technique to analyze the speech signals. This paper presents the literature work available related to speech recognition using fuzzy techniques.
