Three-dimensional reconstruction of the palate and tongue during the production of sustained vowels
Kenneth L. Watkin · The Journal of the Acoustical Society of America · 1991
The purpose of the present investigation was to reconstruct the three-dimensional (3-D) shape of the oral cavity during the production of sustained vowels. Using a specially developed palatal tracing wand and ultrasonic transducer localization device, real time convex phase array images of the tongue were digitized and stored on an IBM PC/AT along with the 3-D shape of the palate. The reconstructed 3-D shapes of the tongue surface relative to the 3-D shape of the palate will be presented. Data analysis strategies will be discussed along with implications for speech articulatory modeling.
