Abstract

A three-dimensional tongue trajectory was reconstructed using multiplaner paced sonography to investigate biomechanical aspects of tongue movement - surface velocity and functional segmentation. The functional segments in tongue movement were identified using principle component analysis. Ultra-CATS software tool developed semi-automatic tongue contour tracings and helped to analyze the speech data. The method enabled the analysis of speech disorders resulting from structural defects or neurogenic movement disorders.
