The coordination change of the lip-jaw system under the upward perturbation condition was investigated. The directional difference between the upward and downward perturbation was also examined. An extended lip-jaw model, which could explain the directional difference was proposed. The stiffness between the different perturbed direction was compared by calculating the relative stiffness. The results show that muscle linkage and labial contact contribute to the coordination among articulators during speech.
