An electropalatograph for speech training and the like, which electrically detects linguapalatal contact mode during phonations by means of many contact sensing electrodes provided on a surface with which trainee's tongue contacts of artificial palate device mounted to hard palate surface of the trainee, detected informations denoting the contact mode are transmitted as electromagnetic waves from a transmitter disposed within the trainee's mouth, and transmitted waves are received by a receiver disposed outside the trainee's body and displayed to be observed as dynamic patterns of actual linguapalatal contact mode.
