Intonation as an encoder of speaker certainty: information and confirmation yes-no questions in Catalan.

Recent studies in the field of intonational phonology have shown that information-seeking questions can be distinguished from confirmation-seeking questions by prosodic means in a variety of languages (Armstrong, 2010, for Puerto Rican Spanish; Grice & Savino, 1997, for Bari Italian; Kügler, 2003, for Leipzig German; Mata & Santos, 2010, for European Portuguese; Vanrell, Mascaró, Prieto, & Torres-Tamarit, 2010, for Catalan). However, all these studies have relied on production experiments and little is known about the perceptual relevance of these intonational cues. This paper explores whether Majorcan Catalan listeners distinguish information- and confirmation-seeking questions by means of two distinct nuclear falling pitch accents.
