In this paper, we present preliminary results of an articulatory study of pharyngealized phonemes in Arabic using an electromagnetic articulograph (AG500). We compared the articulations of pharyngealized phonemes to non-pharyngealized ones. The articulation of the tongue was tracked by four sensors glued onto the tongue. A corpus of several CVCVCVs was recorded using the AG500, labeled, and analyzed. The main finding of this work is that while the main articulation of the tongue is actually moving towards a dental position, the secondary articulation of backing of the tongue can be observed.
