Extracting articulator movement parameters from a videodisc-based cineradiographic database

Mark K. Tiede, Eric Vatikiotis-Bateson

The recent transfer of a selection of cineradiographic movies of the vocal tract to the laserdisc format has now made the application of standard video processing techniques to such data feasible on inexpensive microcomputers. This research explores some of the possibilities inherent in this new look at old data: we have developed software capable of automatically reducing noise, detecting air-tissue boundaries, and tracking articulator displacements (e.g. jaw, lips, tongue) through successive frames. Our goal is to characterize tongue dynamics in terms of changes over time to a normalized parameterization of the tract surface profile. This information will complement other modes for investigating speech production for which either dynamics or surface profiles are unavailable (MRI, magnetometer).
