The model systems of electropalatograph

Abstract

Speech station is used by the speech therapist in rehabilitation of a range of communication disorders. It is the combination of three types of speech therapy devices, which are Laryngograph (Electroglottograph), Nasal Airflow System and Electropalatograph (EPG). These three types of devices used different concepts to detect and analyzed the speech abnormalities of the patient. Laryngograph detect the vibrations of the vocal fold as well as simple movement of glottis, nasal air flow measures both nasal and oral airflow, EPG detects the contact between the tongue and palate, during speech. With the assistance of the speech station, the effectiveness of speech therapy is much more improved. Electropalatograph is an electropalatography system. It detects and displays the dynamic motion of the tongue by using an artificial palate applied on the roof of the mouth. The artificial palate is custom made. The tongue contacts are displayed in tongue-palate contact patterns.
