Abstract :
A methodology for suppressing musical noise produced by signal subspace speech enhancement is presented. An auditory post-filter is placed at the output of the subspace filter to smooth the enhanced speech spectra. By utilizing a perceptual filter, averaging is performed in a manner similar to that of the human auditory system. As such, distortion to the underlying speech signal is reduced.
