Creaky Voice and Prosodic Boundaries in Spanish: An Acoustic Study

Abstract

Abstract This study investigates vocalic creak in connection to the demarcation of prosodic boundaries in Spanish. Data from a picture task from 10 native Spanish speakers from diverse dialects was examined word-medially and word-finally. A total of 800 vowels were analyzed acoustically to determine if they involved creak; duration of creak relative to vowel duration was also recorded. The role of prosodic context, vowel quality and gender were examined. Our results show that creak is one of the cues that signals the end of prosodic constituents, particularly at higher prosodic levels: it averages 64% of realizations word-finally, but only 4% medially; and it is more pervasive in higher prosodic domains. Creak is more likely in males than females (80 vs. 53%), and vowel quality has no effect on creak word-finally, although word-medially /a/ is more frequently creaked than other vowels. We discuss the implications of our results in comparison with previous studies on creaky voice in Spanish and English, in particular Garellek, Marc & Patricia Keating. 2015.
