abstract = {After giving a brief review of the underlying technologies electro-palato- graphy and optical palatography, this paper presents the prototype of a device that combines electrical and optical palatographic measurements to reconstruct the tongue surface during articulation in real-time. The prototype consists of a mouth piece (pseudo-palate) and a control board, and improves on a previous design by integrating the entire measurement system into a single unit, increasing spatial res- olution by a greater number of sensors, and reducing the number of wires necessary to contact the pseudo-palate for more comfortable use. Furthermore, a concept to approximate and visualize the tongue surface from the sensor readings using cu- bic spline interpolation is described. Future challenges in the next development stages are highlighted. The outlined system could be applied in, e.g., experimental phonetics, speech therapy, silent speech interfaces, and pronunciation training.},
