Cantilever-type force-sensor-mounted palatal plate for measuring palatolingual contact stress and pattern during speech phonation

چکیده
A 15-cantilever-type force-sensor unit is presented for the measurement of palatolingual contact stress and pattern during palatal consonant phonation. The force sensor unit is composed of a strain gauge and a cantilever, and is embedded in a thin palatal plate attached to the human hard palate. It is 3 mm wide, by 5 mm long, and 1.3 mm thick. The output of the force sensor unit at the low stress range of 0-64 kPa (0-5 gw) is proportional to the stress applied to the force sensing unit, with nearly no hysteresis. Measurement error of the force sensor is less than 1.7%. Error by mechanical interference among cantilever-type force sensors is less than 0.2%. The presented 15-cantilever-type force-sensormounted palatal plate allows for ready observation of the dynamic aspect of the palatolingual contact stress and patterns during the phonation of consonants.

This paper describes a new method for measuring the tonguepalatal contact pressure using a thin pressure sensor and its application for speech research. The new pressure sensor is composed of thin pressure sensitive ink whose electrical resistance is proportional to the physical forces applied to the sensor. Several sensors were arranged on the surface of the palatal plate. This setup was used ...
