In a study of American English palatals, acoustic characteristics of allophones with different derivational histories were compared. In examples such as 'toss sheepskins' versus 'josh Sheila,' palatalization was found to be complete, as observed in a spectral analysis, and no rearticulation was found. However, the [ess_with_hacek] derived from a sequence of two [ess_with_hacek]'s was observed to exhibit longer duration values than the s from an s[ess_with_hacek] sequence, in keeping with the underlying, intrinsic segment duration values (cf. also, Zue and Shattuck-Hufnagel, 1980). The results suggest that a production/perception theory should model the underlying segment along with the assimilation process. The data were collected from a corpus of 60 sentences each read by eight adult male speakers. [Work supported, in part, by DARPA-ISTO.] [ABSTRACT FROM AUTHOR] |
