An investigation on pitch Synchronous based speech Enhancement using certain Transformations and filtering Techniques

Abstract

Robustness of environmental noise has been an everlasting problem newlinein the widespread deployment of speech enabled services such as speech newlinerecognition and speaker identification systems In communication newlineenvironments the speech signal is affected by various additive background newlinenoise which results in performance degradation For these reasons more newlineeffort has been devoted towards developing efficient speech enhancement newlinealgorithms The main aim is to enhance the apparent quality of the speech and newlineto improve the intelligibility for accurate information exchange For the past newlinetwo decades several speech enhancement techniques have been developed newlineproviding better clarity speech signals but still there is scope for newlineimprovement newline newline
