摘要: On the basis of simulations carried out with a finite element biomechanical model face, influence muscle stress stiffening effect was studied for protrusion/rounding lips produced Orbicularis Oris (OO). It is shown that influences lip shape. When modeled, variation in crucial geometrical characteristics shows clear saturation as OO activation level increases. Similarly, sufficient amount activation, observed when In both cases, differences shaping associated absence or presence have consequences spectral speech signal obtained French vowel /u/. These results are interpreted terms their motor control strategies underlying gesture production.
