Abstract: 

This study presents a technique for noise reduction in speech signals adapting the wavelet transform by comparing it with the power spectral subtraction. To validate the results, segmented signal noise and Itakura Saito distance relationship were used. After analyzing the obtained results, we have verified that the technique based on Wavelet transform showed lower spectral distortion and, in some cases, a better signal to noise ratio.
