Speech enhancement by noise driven adaptation of perceptual scales and thresholds of continuous wavelet transform coefficients

Abstract

This paper focuses on employing adaptive scales for computation of perceptually scaled continuous wavelet transform coefficients (CWT) and adaptive thresholding of these coefficients for speech enhancement. The adaptive scales and thresholds both were decided on the basis of the noise level of the noisy speech signal. The CWT coefficients were scaled… (More)
