点跟踪技术提供了关于舌头的结构运动的定时信息。成像技术提供有关横截面和咽舌的形状和运动的信息。这项研究将这些技术结合在一个单一的主题中。使用X射线微束跟踪舌头表面上的五个小球，并使用实时超声对舌头的正中矢状面和冠状面进行成像。语音材料是VCVCe话语中辅音[s]和[l]以及元音[i]、[a]和[o]的组合。分析集中在与两个辅音相关的舌运动的差异。建立了舌运动模型，其中辅音形状和位置的关键特征主导了舌的张开运动。在该模型中，舌在矢状面和冠状面中被分成称为“功能段”的子部分。功能分部的变动创造了可观察到的开盘变动模式。
Point-tracking techniques provide timing information about structural movements of the tongue. Imaging techniques provide information about cross-sectional and pharyngeal tongue shape and movement. This study joined these techniques in a single subject. Five pellets on the tongue surface were tracked using x-ray microbeam, and the midsagittal and coronal planes of the tongue were imaged using real-time ultrasound. The speech materials were the consonants [s] and [l] and the vowels [i], [a], and [o] combined in VCVCe utterances. Analyses concentrated on the difference in tongue movements related to the two consonants. A model of tongue movement was developed, in which critical features of consonant shape and position dominated the tongue opening movement. In this model, the tongue is divided into subdivisions termed "functional segments" in both the sagittal and coronal planes. Movements of the functional segments created observable opening movement patterns.
