Platform EMA - Electromagnetic Articulography Acquisition

Functional Description: Since the purchase of the articulograph AG500 in 2007, we have built a strong experience with respect to the acquisition technique and we have developed an acquisition protocol. The platform has been improved by acquiring the latest articulograph AG501 funded by the EQUIPEX ORTOLANG project. The AG501 allows tracking the movement of 24 sensors at reasonable high frequency (250Hz) up to a very high frequency (1250Hz). In addition, we have continued improving VisArtico (cf. 6.5 ), a powerful tool to visualize articulatory data acquired using an articulograph. This year we have used the system to acquire articulatory data for the tongue, jaw and lips to study stuttering speech disorder (informal collaboration with F. Hirsch, Praxiling (UMR 5267)). We have also used the EMA platform to acquire motion capture data for the lips, to be used in the context of audiovisual speech synthesis [82] .
