Kristine Yu presented an invited talk on “Building Phonological Trees” at the Eighteenth SIGMORPHON Workshop on Computational Phonology, Morphology, and Phonetics on August 5th 2021. An abstract is below.

Computational perspectives from string grammars have richly informed our understanding of phonological patterns in natural language in the past decade. However, a prevailing theoretical assumption of phonologists since the 1980s has been that phonological patterns and processes are computed on trees built with prosodic constituents such as syllables, feet, and prosodic words. This talk explores how perspectives from tree grammars can provide insight into our understanding of prosodic representations, including different ways in which tones can enter the grammar.
