The Berkeley Phonetics and Phonology Forum ("Phorum") is a weekly talk and discussion series featuring presentations on all aspects of phonology and phonetics. 

We meet Mondays 12-1pm in 1303 Dwinelle.

Phorum is organized by Myriam Lapierre and Eric Wilbanks. Our emails are respectively "myriam.lapierre" and "wilbanks_eric"

November 26, 2018 - Simon Todd: Word frequency effects in sound change: A listener-based exemplar model

Word frequency effects in regular sound change present a major unresolved puzzle. The literature has documented cases of regular sound change in which high-frequency words change faster than low-frequency words, other cases in which they change slower than low-frequency words, and yet other cases in which all words change at the same rate. How can these differences be explained? I propose that the answer lies in the implications of the change for the listener. I present an exemplar-based computational model of regular sound change in which the listener plays a large role, and I demonstrate that it generates sound changes with properties and word frequency effects seen empirically in corpus data. In particular, I show that the various word frequency effects in the literature follow from a single perceptual asymmetry, whereby a listener can more easily recognize high-frequency words than low-frequency words when acoustically ambiguous. Different word frequency effects arise in different kinds of sound changes because they change the listener's landscape of acoustic ambiguity in different ways.
