Abstract : Speech production is a dynamic process which relies on the realization of articulatory gestures by the speaker. Its study thus necessitates technologies to acquire articulatory data, which often come from medical imaging. Xrays have been used until the end of last century. These data are films which require processing before being exploited. Xarticulators software was developed for this purpose and it enables the manual or automatic extraction of articulator contours. This communication presents the database collected at IPS, the protocol used to process data and the construction of articulatory models intended to approximate the vocal tract shape for vowels and consonants. We detail the improvement of the model in the cases of consonants so as to offer a good geometric precision at the place of articulation, and thus a correct acoustic signal with articulatory synthesis. This communications ends with the presentation of articulatory copy synthesis tools which enable realistic speech to be synthesized from images of an Xray film of the vocal tract.
