A Biologically Motivated Solution to the Cocktail Party Problem
We present a new approach to the cocktail party problem that uses a cortronic artificial neural network architecture (Hecht-Nielsen, 1998) as the front end of a speech processing system. Our approach is novel in three important respects. First, our method assumes and exploits detailed knowledge of the signals we wish to attend to in the cocktail party environment. Second, our goal is to provide...
متن کاملAuditory Perception: Attentive Solution to the Cocktail Party Problem
A recent study has demonstrated how the focus of auditory attention can rapidly shift to follow spectrally dynamic speech-like sounds in the presence of a similar interferer. This requires multidimensional variation in sound features and a minimum spacing in spectral feature space.
متن کاملThe cocktail party problem
Natural auditory environments, be they cocktail parties or rain forests, contain many things that concurrently make sounds. The cocktail party problem is the task of hearing a sound of interest, often a speech signal, in this sort of complex auditory setting (Figure 1). The problem is intrinsically quite difficult, and there has been longstanding interest in how humans manage to solve it. The p...
متن کاملThe Cocktail Party Problem
This review presents an overview of a challenging problem in auditory perception, the cocktail party phenomenon, the delineation of which goes back to a classic paper by Cherry in 1953. In this review, we address the following issues: (1) human auditory scene analysis, which is a general process carried out by the auditory system of a human listener; (2) insight into auditory perception, which ...
متن کاملSparse representations for the cocktail party problem.
A striking feature of many sensory processing problems is that there appear to be many more neurons engaged in the internal representations of the signal than in its transduction. For example, humans have approximately 30,000 cochlear neurons, but at least 1000 times as many neurons in the auditory cortex. Such apparently redundant internal representations have sometimes been proposed as necess...
