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.}, number={4}, journal={Canadian Acoustics}, author={Flowers, Heather and Bressmann, Tim and Carmichael, Brent and Heng, Chiang-Le and Wong, Willy}, year={2005}, month={Dec.}, pages={50–51} }
