Inter-speaker variation, Optimality theory, and the prosody of clitic left-dislocations in Spanish

Abstract

AbstractThis paper presents an empirical study on the prosody of clitic left-dislocations (CLLDs) in Spanish and offers new perspectives on how the phenomenon of inter-speaker variation in linguistic data can be integrated into formal grammatical theory. Results from a production experiment based on scripted speech show that CLLDs have an obligatory left and right boundary (typically a high edge tone at the intermediate phrase level), while other sentence-internal boundaries are subject to inter-speaker variation. The hypothesis presented here suggests that prosodic boundaries which mark information structural (IS) categories are more necessary than boundaries which satisfy alignment constraints; only the latter can show inter-speaker variation (
