چکیده

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 preprocessing in advance of a pattern recognition system rather than to separate one or more of the mixed sources explicitly. Third, the neural network model we employ is more biologically feasible than are most other approaches to the cocktail party problem. Although the focus here is on the cocktail party problem, the method presented in this study can be applied to other areas of information processing.

The 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 ...

Cocktail Party Problem: Source Separation Issues and Computational Methods

The concept of the cocktail party problem (CPP) was coined by Cherry (1953). It was proposed to address the phenomenon associated with human auditory system that, in a cocktail party environment, humans have the ability to focus their listening attention on a single speaker when multiple conversations and background interferences and noise are presented simultaneously. Many researchers and scie...

Auditory 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.

Cocktail Party Processing via Structured Prediction

While human listeners excel at selectively attending to a conversation in a cocktail party, machine performance is still far inferior by comparison. We show that the cocktail party problem, or the speech separation problem, can be effectively approached via structured prediction. To account for temporal dynamics in speech, we employ conditional random fields (CRFs) to classify speech dominance ...

Frogs Exploit Statistical Regularities in Noisy Acoustic Scenes to Solve Cocktail-Party-like Problems

Noise is a ubiquitous source of errors in all forms of communication [1]. Noise-induced errors in speech communication, for example, make it difficult for humans to converse in noisy social settings, a challenge aptly named the "cocktail party problem" [2]. Many nonhuman animals also communicate acoustically in noisy social groups and thus face biologically analogous problems [3]. However, we k...
