This research focuses on the study of the multidimensionality of the visible articulatory movements in the production of the Italian stressed and unstressed vowels. Lip and jaw movements were recorded and analysed with a fully automatic real-time system for 3D kinematics data acquisition. The data obtained show that jaw opening and lower lip protrusion were the most relevant articulatory parameters in distinguishing among the vowels.
