Speech Denoising and Speech Enhancement Using Wavelet Filter
Kavita Sharma · IOSR Journal of Engineering · 2012
Speech plays an important role in multimedia system.Speech enhancement is to remove noise from speech for multimedia systems.Noise is an unwanted interference in any form of communication generally degrades the quality of the information signal.During transmission and reception signals are often corrupted by noise which can cause severe problems for downstream processing and user perception.Therefore an automated means of removing the noise would be an invaluable first stage for many signal processing tasks.Denoising has long been a focus of research and yet there always remains room for improvement.There are so many techniques to improve the signal quality or to regenerate the signal.In this paper we present a method for speech denoising using wavelet filter.Firstly the speech is recorded using matlab and played, finally the recorded speech is processed using wavelet filter.
