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.
Claims15
An electropalatograph comprising an artificial palate formed of an insulative material in a configuration substantially coinciding with the hard palate of a person speech-trained,
- said artificial palate having a plurality of signal-transmitting electrodes distributed substantially over an entire surface of the artificial palate to sense an actual linguapalatal contact during a phonation and a single signal-receiving electrode provided to contact with the hard palate as insulated from said signal-transmitting electrodes,
- means for scanning sequentially respective said plurality of signal-transmitting electrodes with a series of signals, and
- means for recognizing a pattern of at least said actual linguapalatal contact on the basis of said scanning signals received by said signal-receiving electrode as transmitted from certain ones of the signal-transmitting electrodes which have sensed the linguapalatal contact.
