An artificial palate device of electropalatographs for electrically detecting and observing dynamic patterns of linguapalatal contacts during speeches by means of many tongue-contact sensing electrodes provided on a tongue-contacting surface of the device fitted intimately to the surface of hard palate of trainees of articulation study and speech training. The electrodes and lead wires connecting the electrodes to an electropalatograph display device are provided on a surface of base board preliminarily prepared with a flat, electrically insulative and flexible plate material and in a shape intimately adaptable when curved to the hard palate. As required, a flat metal foil easily deformable in sectional shape and retainable in its deformed shape is laminated in the other surface of the base board. The lead wires and metal foil are covered by an insulative layer. |
