In this article, we examine the effects of changing speaking rate and syllable stress on the space-time structure of articulatory gestures. Lip and jaw movements of four subjects were monitored during production of selected bisyllabic utterances in which stress and rate were orthogonally varied. Analysis of the relative timing of articulatory movements revealed that the time of onset of gestures specific to consonant articulation was tightly linked to the timing of gestures specific to the flanking vowels. The observed temporal stability was independent of large variations in displacement, duration, and velocity of individual gestures. The kinematic results are in close agreement with our previously reported EMG findings [B. Tuller et al., J. Exp. Psychol. 8, 460-472 (1982)] and together provide evidence for relational invariants in articulation.
在本文中，我们研究了语速和音节重音的变化对发音动作时空结构的影响。在选定的双音节话语产生过程中，对四名受试者的嘴唇和下颚运动进行了监测，其中重音和语速是正交变化的。发音动作相对时间的分析表明，辅音发音特有的动作起始时间与相邻元音特有的动作时间紧密相关。观察到的时间稳定性与单个动作在位移、持续时间和速度上的巨大变化无关。运动学结果与我们之前报道的肌电图研究结果[B. 图勒等人，《实验心理学杂志》8，460 - 472(1982)]密切一致，共同为发音中的关系不变性提供了证据。
