COMPUTATIONAL AUDITORY SCENE ANALYSIS - EXPLOITING PRINCIPLES OF PERCEIVED CONTINUITY

Acoustic sources are often occluded by other sounds, yet the strategie s for recovering individual sources employed by the auditory system in tasks such as speech recognition are remarkably robust against these intrusions. There are often sufficient cues which allow the auditory s ystem to determine whether sound components continue through such occl usions. This paper reviews the situations where an assumption of conti nuity is warranted and demonstrates how the principles governing the s o-called ''continuity illusion'' can be used within a computational sy stem for segregating acoustic sources.
