Abstract
In this paper results are presented concerning the use of spectral subtraction for enhancing speech corrupted by additive noise. In this study several variations of the spectral subtraction process have been implemented and tested. The overall results provide insight into the use of spectral subtraction for speech enhancement. As a result of this study, several conclusions are presented regarding spectral subtraction, its effects on noise corrupted speech, and its ability to enhance speech intelligibility and listenability. Finally, the use of spectral subtraction as a preprocessor for speech feature extraction is considered.
