Speech segregation: problems and perspectives
Chris Darwin
(University of Sussex)
The talk will first discuss how the hierarchical nature sound sources relates to the problem of grouping speech sounds and the nature of the contraints that might appropriately be applied at different levels. It will then move on to look in more detail at how spatial cues are used in the organisation of speech sounds, including both problems of simultaneous and sequential organisation and in determining the continuity of complex sounds.
