Abstract
A noise suppressor detects a peak position in the frequency spectrum of an input speech signal, and masks frequency components in the spectrum as a function of the peak position. The masking process attenuates or removes frequency components near the peak position if their magnitudes are significantly lower than the magnitude of the spectrum at the peak position. This noise suppressor effectively removes irregular noise from the spectrum while leaving enough of the spectrum to reproduce the speech signal clearly.
