Abstract
An electropalatograph wherein a plurality of signal-transmitting electrodes on an artificial palate for detecting linguapalatal contact pattern are scanned sequentially in a predetermined order with a series of scanning signals, transmitted signals from actually contacted ones of the signal-transmitting electrodes to a single signal-receiving electrode on the artificial palate and contacting with the user's hard palate are sequentially detected by a single detector, and detected signals identifying the actually contacted electrodes are employed to dynamically indicate the pattern. To increase detection accuracy, the detected signals are compared with standard linguapalatal contact data, optionally with a modification of such data to provide an allowance in accuracy determination.
