This paper presents a description of the APEX speech production model and some of its main current capabilities. We describe an ongoing X-ray project initiated to calibrate APEX according to individual speaker characteristics and to obtain data on how articulatory movements are coordinated in the coarticulation of Swedish vowels and stops. The mapping of the X-ray data onto APEX parameters is also illustrated.
