The goal is to study biomechanical constraints of the tongue and examine its dependence on the hard palate. The first set of studies will distinguish between acoustically and biomechanically driven tongue behaviors by mapping the 3D geometry of tongue motion in normal and deaf speech. A second set of studies will use ultrasound and electropalatography to examine tongue gestures and their tongue-palate contact patterns to define the effects of tongue-palate "bracing" on tongue shape, in a cross-linguistic study. A third study will examine tongue-palate interaction in swallowing, to eliminate linguistic effects. This project is important because although critical to speech, swallowing and breathing, the tongue as a movement system is poorly understood.

目的是研究舌头的生物力学约束并检查 它的依赖对硬口味。 第一组研究将 区分声学和生物力学驱动的舌头 通过绘制舌头运动的3D几何形状以正常和聋哑 演讲。 第二组研究将使用超声波和 电视检查以检查舌头手势及其舌头 接触模式来定义舌片“支撑”对 在一项跨语言研究中。 第三项研究将检查 吞咽中的舌头相互作用，以消除语言影响。 这个项目很重要，因为尽管对语音至关重要，但吞咽 呼吸，舌头作为运动系统的理解很少。
