Phorum

The Berkeley Phonetics, Phonology and Psycholinguistics Forum ("Phorum") is a weekly talk and discussion series featuring presentations on all aspects of phonetics, phonology, and psycholinguistics. We meet on Mondays from 12(:10)-1pm (unless specified otherwise below), in Dwinelle 1229 (Zoom link shared upon request). Phorum is organized by Kai Schenck. My email is "kai_schenck" @berkeley.edu.

Schedules from previous semesters can be found here.

Fabián Leonardo Malaver Chaparro (UC Berkeley): Stress-conditioned allomorphies in Korebajʉ  

This talk examines two prosodically conditioned allomorphic alternations in Korebajʉ, a Western Tukanoan language of the Colombian Amazon: a copular morpheme (-a ~ ∅) sensitive to the stress of the preceding syllable, and a negation morpheme (-ma ~ -mane) sensitive to the parity of syllables following it within its phase. Both patterns seem to require phonology and morphology to see across their usual boundary, a problem for modular grammars. Using corpus data from Cook & Criswell (1993) and Cook (1999), I show both alternations follow naturally within Cophonologies by Ph(r)ase, where exponent selection depends only on the metrical structure of the immediately preceding phase. The negation pattern additionally motivates a high syntactic base for the morpheme, in tension with the Mirror Principle. The results argue that Korebajʉ's iambic stress system is synchronically active, not a fossilized historical residue.

Gašper Beguš (UC Berkeley): Heavy syllable endings and the origin of Pre-PIE mobility

Proto-Indo-European featured a complex system of accentual and ablaut paradigms. In this paper, I outline a proposal for the development of accentual mobility in Pre-PIE. The accent-ablaut system is mostly described as morphologically conditioned, but its diachronic origin is likely phonetic. Based on the behavior of the most archaic lexical and morphological layer, root nouns and verbs, I argue that ending morphemes with heavy syllables attracted stress, which results in accentual mobility. While the rule was not phonetically active in PIE, it leaves traces and allows us to explain some forms that were difficult to explain. The rule also provides a simple phonetic motivation for a complex morphophonological system of PIE accentual mobility.
