A Strain Gage Transduction System for Lip and Jaw Motion in Two Dimensions: Design Criteria and Calibration Data
James H. Abbs, Bruce N. Gilbert · Journal of Speech and Hearing Research · 1973
A strain gage system was designed and constructed for transducing the movements of the lips and jaw in two dimensions during speech. Measurement of the structural loading factor, frequency response, linearity, and phase response of this system suggests that it provides a favorable alternative to some earlier lip and jaw monitoring devices. Some examples of the movement records obtained with this transducer system are provided.
