Definition : Recorders designed to measure and record the timing and location of tongue contact with the hard palate during normal speech (i.e., electropalatography, also known as palatometry). These recorders typically include an artificial palate that is molded to fit the roof of the mouth, electrical contacts located on the lingual surface of the artificial palate, connectors to link the artificial palate to a computerized unit, dedicated software to process the information, and a recorder of the tongue-palate contact patterns synchronized with acoustic recording of the speech. Electropalatographs are intended for research, clinical studies, and assessment of speech therapy.
