Posture is fundamental to motor control. Body posture acts as a reference frame for planning all intentional movements and is essential for completing tasks and daily functions. Speech production involves motor control of many different body parts, yet postural control for speech has not been widely discussed. Our lab investigates how posture provides the substrate on which speech production is built. This research addresses questions such as how speech postures coarticulate with both transient movements and other postures (such as facial expression), and how structures such as the lips, tongue, soft palate, and larynx move during or between utterances.
