In order to more completely understand speech production and the underlying sensorimotor control, a number of complementary approaches are needed. The following focuses on methods for examining the spatiotemporal dynamics of speech production to infer characteristics of the underlying neural control processes. Data are presented on the precision with which different speech articulators are controlled, the variation in control precision as a function of phonetic context, and a method for examining kinematic variation as a function of time. Results highlight the dynamic multivariate nature of the speech production process.
