One of the most recent methods for speech articulators assessment is the Electromagnetic articulography (EMA). By correlational and regressive analysis of signals from articulograph and video camera it becomes possible to determine relationships between motion of internal and external speech articulators. This in turn is important for visual to articulatory speech inversion - the method allowing to estimate inner articulators movement without using aticulograph. This paper presents correlation analysis between video markers motion trajectory and trajectories for EMA sensors placed on upper and lower lip. Correlational and regressive relationships between external and internal EMA sensors have been presented too. Strong correlational and regressive dependencies between EMA sensor movements have been observed.
