Abstract

The ability of a binaural listener to concentrate on speech from a particular location whilst preferentially suppressing speech from other locations has been termed the binaural "cocktail party" effect. The recently developed unsupervised artificial neural network models for blind signal processing have provided additional perspectives on the binaural cocktail party effect. This paper presents a model of the cocktail party effect based on a temporal anti-Hebbian adaptive maximum likelihood estimator. The complicating effects of reverberation and physically non-stationary speech sources on unwanted speech suppression are empirically investigated. (C) 1998 Elsevier Science B.V.
