| Abstract: | An approach to speech-sound enhancement is proposed based on the spectral subtraction.The masking of the auditory system is used to determine the value of each frame dynamically and the enhancement is performed selectively.The experiment result shows that the approach restrains from the background noise and music residual noise and improved the speech-sound quality. |
