Multi-Input Strictly Local Functions for Tonal Phonology


This paper presents an automata-theoretic characterization of the typology of attested tonal patterns using enriched data structures. We generalize the Input Strictly Local class of functions to consider multiple inputs of tonal and segmental strings, and find that the associated strictly local multi-tape transducers successfully capture tonal typology. Links between automata-theoretic and logical characterizations of phonological expressivity showcase tradeoffs in data structure and locality in the expressivity of phonological computation.
