Abstract

The concept of displaying tongue contact with the roof of the mouth via a matrix of electrodes embedded in a plastic palate has existed for over 20 years. From a simple array of lights to display the contact patterns, systems have developed to an IBM PS/2 personal computer, and software written to allow storage and playback of EPG (electropalatography) displays with graphical analysis of contact data. The therapist can produce and display a visual pattern of a specific sound for the patient to try and copy. The complete system consists of the palate, plugged into a multiplexer box, which is worn around the neck and leads to a PS/2 personal computer.
