Extraction des mouvements du conduit vocal à partir de données cinéradiographiques
Julie Fontecave, Frédéric Berthommier.
Since high speed X-ray films still provide the best dynamic view of the entire vocal tract, large existing databases have been preserved and are available for the speech research community. We propose a new technique for automatic extraction of vocal tract movements from these data. At first, the method was developed for the extraction of tongue movements in Wioland recorded in Strasbourg in 1977. Then, the same technique was adapted to other articulators and other X-rays films, taking into account their specificities. Finally, a quantitative evaluation of the estimate error and a comparison with Thimm and Luettin (1999) are achieved.
