A computational model of auditory scene analysis
نویسندگان
چکیده
Various grouping attributes have been translated into successful signal processing techniques that may be used in source separation, e.g., to separate speech from background. However, separation is not enough to know: What is the source of the sound? A next step beyond primitive ASA is schema-based ASA, to give meaning to the source, i.e. to map bottom-up audio features to the meaningful content of an auditory scene. 2 Network models

Bregman's Chimerae: Music Perception as Auditory Scene Analysis
Research into the perception and cognition of music listening often contains implicit assumptions about the nature of the underlying mental representations, and about the relationship between "auditory processing" and "music perception". We attempt to highlight and problemitize some of these assumptions and to provide a more cognitively appropriate model for music perception and cognition, base...
متن کاملA blackboard architecture for computational auditory scene analysis
A challenging problem for research in computational auditory scene analysis is the integration of evidence derived from multiple grouping principles. We describe a computational model which addresses this issue through the use of a `blackboard' architecture. The model integrates evidence from multiple grouping principles at several levels of abstraction, and manages competition between principl...
متن کاملOn Amplitude Modulation for Monaural Speech Segregation
We propose a computational auditory scene analysis (CASA) model for monaural speech segregation. It deals with low-frequency and high-frequency signals differently. For high-frequency signals, it generates segments based on common amplitude modulation (AM) and groups them according to AM repetition rates. This model performs substantially better than previous CASA systems.
متن کاملAuditory Scene Analysis: Computational Models
Listeners have to make sense of a complex acoustic world containing overlapping sound sources that must be organized into individual auditory objects. Computational auditory scene analysis concerns the use of algorithms inspired by human sound perception whose aim is to extract properties of constituent sound sources in a complexmixture. Starting with representations based on models of how soun...
متن کاملThe auditory organization of speech and other sources in listeners and computational models
Speech is typically perceived against a background of other sounds. Listeners are adept at extracting target sources from the acoustic mixture reaching the ears. The auditory scene analysis account holds that this feat is the result of a two stage process. In the first stage, sound is decomposed both within and across auditory nuclei. Subsequent processes of perceptual organisation are informed...
متن کاملConnectionist Models for Auditory Scene Analysis
Although the visual and auditory systems share the same basic tasks of informing an organism about its environment, most connectionist work on hearing to date has been devoted to the very different problem of speech recognition . VVe believe that the most fundamental task of the auditory system is the analysis of acoustic signals into components corresponding to individual sound sources, which ...
