Speaker: Rachel Walker (USC)
Title: Temporal Structure in Phonology
Time: Friday, February 24th, 3:30-5:00 pm
Venue: 32-155
Abstract:

In phonological structure, the segment root node is classically the locus of temporal organization for sub-segmental units, such as features, governing their sequencing and overlap (e.g. Clements 1985, Sagey 1986). Segment root nodes also classically mediate hierarchically between moras and sub-segmental elements, and by structurally identifying segments, roots figure in the calculation of weight-by-position, where coda consonants are assigned a mora (Hayes 1989). In this talk, I discuss evidence from phonotactic patterns that motivate an enriched representation of temporal relations, where coordination is represented directly among sub-segmental elements. Weight-by-position is also calculated over this sub-segmental temporal structure. In light of these representations, I consider implications for segment roots and suggest that root nodes be eliminated in favor of a set-based understanding of segments, extending set-based notions of feature classes (Padgett 2002).
