Sound stream segregation: a neuromorphic approach to solve the “cocktail party problem” in real-time
The human auditory system has the ability to segregate complex auditory scenes into a foreground component and a background, allowing us to listen to specific speech sounds from a mixture of sounds. Selective attention plays a crucial role in this process, colloquially known as the "cocktail party effect." It has not been possible to build a machine that can emulate this human ability in real-t...
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 کاملA cocktail party with a cortical twist: how cortical mechanisms contribute to sound segregation.
Sound systems and speech technologies can benefit greatly from a deeper understanding of how the auditory system, and particularly the auditory cortex, is able to parse complex acoustic scenes into meaningful auditory objects and streams under adverse conditions. In the current work, a biologically plausible model of this process is presented, where the role of cortical mechanisms in organizing...
متن کاملUsing auditory pre-information to solve the cocktail-party problem: electrophysiological evidence for age-specific differences
Speech understanding in complex and dynamic listening environments requires (a) auditory scene analysis, namely auditory object formation and segregation, and (b) allocation of the attentional focus to the talker of interest. There is evidence that pre-information is actively used to facilitate these two aspects of the so-called "cocktail-party" problem. Here, a simulated multi-talker scenario ...
