Title of Document: Auditory streaming: behavior, physiology, and modeling Ling Ma, Doctor of Philosophy, 2011 Directed By: Professor Shihab A. Shamma, Department of Electrical and computer Engineering, Institute of Systems Research Auditory streaming is a fundamental aspect of auditory perception. It refers to the ability to parse mixed acoustic events into meaningful streams where each stream ...

We propose an Auditory VOCODER to resynthesize sound from the Auditory Mellin Image which is an auditory representation that segregates the size and shape information of incoming sound. The sound resynthesis part consists of three techniques: the STRAIGHT VOCODER [2], frequency-warping cepstral analysis [4,12], and nonlinear multivariate regression analysis (MRA). We explain these methods and t...

Abstract A better understanding of auditory scene analysis requires uncovering the brain processes that govern the segregation of sound patterns into perceptual streams. Existing models of auditory streaming emphasize tonotopic or “spatial” separation of neural responses as the primary determinant of stream segregation. While partially true, this theory is far from complete. It overlooks the in...

In a complex acoustic environment, acoustic cues and attention interact in the formation of streams within the auditory scene. In this study, a variant of the "octave illusion" [Deutsch (1974). Nature 251, 307-309] was used to investigate the neural correlates of auditory streaming, and to elucidate the effects of attention on the interaction between sequential and concurrent sound segregation ...

Audio stream segregation is a task performed constantly by the human auditory system, yet is difficult to reproduce with a computer. The research detailed in this paper looks at performing just one method of stream segregation the temporal coherence boundary using a fuzzy clustering system. The main focus of the paper is on examining the effectiveness of several time-frequency distributions as ...
