Abstract

Real-time magnetic resonance imaging (rtMRI) provides information about the dynamic shaping of the vocal tract during speech production. 1 We develop a dynamical system in the framework of Task Dynamics 2 which controls vocal tract constrictions and induces deformation of the air-tissue boundary. The system parameterizes the air-tissue boundary through factor analysis of rtMRI videos and characterizes the relation between vocal tract shape and vocal tract constrictions.
