Semi-Automatic Processing of Real-time MR Image Sequences for Speech Production Studies

This paper describes algorithms and data processing procedures developed to process real-time magnetic resonance images for speech production studies. These techniques allow visualization of the teeth, contour tracking over time of active and passive articulators, and vocal tract aperture recovery. These techniques can facilitate speech production studies requiring, for example, the computation of the resonance frequencies of the moving vocal tract or an examination of intergestural timing.
