Abstract
In digital mobile communications several measures are taken beyond speech coding to enhance the perceived quality in the presence of acoustic background noise and transmission errors. In premium mobile phones meanwhile advanced algorithms for noise suppression, error concealment, and finally artificial bandwidth extension come to practical application. It will be shown in this contribution that theses three different concepts of speech enhancement are actually based on the same common principle of conditional estimation, taking statistical a priori knowledge into account. Recent developments in these three areas are presented.
