Abstract This study investigates mechanical cooperation among tongue muscles. Five volunteers were imaged using tagged magnetic resonance imaging to quantify spatiotemporal kinematics while speaking. Waveforms of strain in the line of action of fibers (SLAF) were estimated by projecting strain tensors onto a model of fiber directionality. SLAF waveforms were temporally aligned to determine consistency across subjects and correlation across muscles. The cohort exhibited consistent patterns of SLAF, and muscular extension-contraction was correlated. Volume-preserving tongue movement in speech generation can be achieved through multiple paths, but the study reveals similarities in motion patterns and muscular action—despite anatomical (and other) dissimilarities.

说话时人舌纤维应变分析

摘要 本研究调查舌肌之间的机械合作。使用标记磁共振成像对五名志愿者进行成像，以量化说话时的时空运动学。通过将应变张量投影到纤维方向性模型上来估计纤维作用线 (SLAF) 中的应变波形。SLAF 波形在时间上对齐，以确定受试者之间的一致性和肌肉之间的相关性。该队列表现出一致的 SLAF 模式，并且肌肉伸展收缩相关。语音生成中保持音量的舌头运​​动可以通过多种途径实现，但该研究揭示了运动模式和肌肉动作的相似性——尽管在解剖学（和其他）方面存在差异。
