Abstract

The recent increasing availability of comprehensive real-time MRI data of the vocal tract and concomitant progress in air-tissue boundary segmentation present novel opportunities for articulatory modeling. PCA-based articulatory models represent vocal tract configurations as weighted linear combinations of articulatory components that characterize vocal tract shaping patterns. Historically, most such models have been developed using data from a single speaker, and their direct application to data from multiple speakers may provide components that are not comparable across speakers. A technique that can address this issue is PARAFAC, which has been applied in the past to analyze data corresponding to tongue contour X-ray tracings of 10 English vowels from 5 speakers. PARAFAC introduces an additional level of weighting of the articulatory components that is constant for, and therefore characteristic of …
