关于下颌骨和舌骨的与语音相关的运动涉及旋转和平移的程度，我们知之甚少。数据来自于现有的高速电影放射摄影的27个双音节产生的一个单一的成年男性英语发言人来解决这个问题。下颌骨系统的两个骨性组成部分的相对位置的时间历程表示在相当于矢状面坐标的两个标志上，进行了分析，以确定（a）各自的位置和方向的范围，（B）选定的节段和超节段变量之间的关联，以及这些范围的子区域，（c）咬合架旋转和标志位移之间的相互依赖性。一般来说，从这位发言者的数据，下颌骨和舌骨，是与以前的报告一致的下颌骨单独，所有这些都表明，旋转和平移分量的运动是足够独立的，以保证运动学描述，把这两个结构作为刚体在一个平面上移动。
Relatively little is known about the extent to which speech-related movements of the mandible and hyoid bone involve rotation and translation. Data were derived from an existing high-speed cineradiograph of 27 disyllables produced by a single adult male speaker of English to address this issue. Time histories of relative locations of both bony components of the mandibular system expressed in terms equivalent to the sagittal-plane coordinates of two landmarks on each, were analyzed to determine (a) their respective ranges of position and orientation, (b) associations between selected segmental and suprasegmental variables, and subregions of those ranges, and (c) interdependencies between articulator rotation and landmark displacement. In general, data from this speaker, for the mandible and hyoid bone, are consistent with previous reports for the mandible alone, all of which suggest that rotational and translational components of their motions are sufficiently independent to warrant kinematic descriptions that treat both structures as rigid bodies moving in a plane.
