Linguistics Colloquium: Matt Goldrick, Northwestern University
Abstract: During speech, the positions of the articulators evolve continuously in physical space. In ongoing work, we have proposed that mental representations underlying speech articulation evolve continuously in an abstract symbolic space, organized around the dimensions that define linguistic structure. To support this proposal -- Gradient Symbolic Computation (GSC) -- I will review acoustic phonetic data suggesting multiple planning elements can be co-activated and as a result co-produced in articulation. I will then present new work examining the implications of dynamics for theories of grammar, suggesting that GSC may provide a novel, non-derivational account of opaque phonological processes.
