Silicon Models for Auditory Scene Analysis
نویسندگان
چکیده
We are developing special-purpose, low-power analog-to-digital converters for speech and music applications, that feature analog circuit models of biological audition to process the audio signal before conversion. This paper describes our most recent converter design, and a working system that uses several copies of the chip to compute multiple representations of sound from an analog input. This multi-representation system demonstrates the plausibility of inexpensively implementing an auditory scene analysis approach to sound processing.

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 ...
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 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 کاملTitle : The 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 into collections of fragments in several dimensions. Subsequent processes of perceptual organization ...
