Abstract
This paper proposes a using probe for measuring of contact force between tongue and palatal, during speech. We developed a 0.03 mm-thick stainless steel tongue force probe with a 3x5 mm force sensor at the tip. Linguopalatal contact force was measured by inserting the probe into the oral cavity. Contact force was measured at the following three locations. Based on the coordinate and measurement obtained at the three points, the action point of tongue force was calculated by the weighted mean. Linguopalatal contact force was measured in four adult men and women without articulation disorder and in three adult men with articulation disorders. Results showed that the action point of tongue force in subjects with articulation disorders was further toward the pharynx than that in subjects without articulation disorders. Linguopalatal contact pressure was then measured again by asking the subjects with articulation disorders to wear a palatal augmentation prosthesis (PAP) to compensate for insufficient linguopalatal contact force. The action point of tongue force became better approximated to that of subjects without articulation disorders. Given these results, our simple method for measuring linguopalatal contact force using a tongue force probe appears to be a promising tool for speech therapists treating articulation disorders.
