Title:

Echoes of Cognition in Pronunciation Variation

Abstract:

Language is the key means by which we share our internal thoughts with others. We clearly do this by choosing particular combinations of words to speak. Speech, however, is a very rich source of information, providing many opportunities for communication over and above a sequence of words. I'll discuss work from my research group showing how small changes in the way we pronounce sounds (e.g., elongating or shortening an individual consonant) reflect the internal process of speech planning. When speech is difficult to plan, sounds are distorted in predictable ways, including increases in accent for bilinguals speakers. I'll then discuss how my lab (and the field in general) is moving away from relatively small, expert-annotated data sets to machine learning based methods for automated speech analysis of large corpora. I'll conclude by discussing current work investigating the promise of such methods for understanding mental disorders such as psychosis.
