Resumen de Prosody as a genre-distinguishing feature in Ahtna: A quantitative approach

Andrea L. Berez

• This article is a quantitative examination of the function of prosody in distinguishing between the genres of oral performance and expository discourse in Ahtna, an Athabascan language of south-central Alaska. Within the framework of the intonation unit (e.g., Chafe 1987) I examine features of prosody related to both timing (intonation unit length and duration, pause duration and distribution, and syllable pacing) and pitch (pitch reset, boundary tones, and intonational phrasing). I show to a statistically significant degree that most of the prosodic burden of distinguishing genre is carried by a particular intonation contour that is associated with Ahtna oral performance and causes several measurable distinctions between genres.
