This is a project currently under development in collaboration with Stefanie Shattuck-Hufnagel and Mark Tiede. This project uses speech errors as a window on speech planning and plan optimization processes.  This is because we view speech errors as inherently related to articulatory variability resulting from competition during planning. Motivation for this project came from an older project of ours, in which, together with Christine Mooshamer and Louis Goldstein, we found that planning for the phonemic content of an utterance and planning for the prosodic grouping of its words interact with each other, with aberrant speech emerging from competition between the two.
