3D Electropalatography

3D Electropalatography (EPG) system

LinguaGraph 3D is an electropalatography (EPG) system that uses state-of-the-art computer animation and 3D modelling techniques to illustrate where the tongue touches the hard-palate during speech. The 3D model, which can be rotated 360°, provides direct articulatory information in real-time.
