Abstract

In this paper an algorithm for the reduction of stationary noise in speech signals is proposed. In contrast to the conventional trade-off between distortions of the speech and noise components the primary goal of the presented algorithm is to attenuate the noise by a pre-defined factor and to conceal artifacts and distortions of the residual noise by taking advantage of the auditory masking threshold. In this way it can be achieved that the spectral colour of the attenuated noise is the same as that of the background noise in the input signal. Informal listening tests and instrumental evaluations with several quality measures have been performed to compare the new weighting rule with conventional approaches.
