在4名正常说话的成年人中，用应变计系统测量了上唇、下唇和下颌的上下位移。比较了上唇和下唇在下颌自由移动和使用咬块将下颌固定在四个不同垂直位置的情况下的运动。随着咬块的增加，下颌张开位置的增加，发现：(a)双唇闭合的位置发生变化，但不同咬块大小的双唇闭合运动通常不保持一致的比例；(b)尽管唇部在许多情况下保持相当一致的最大唇间开口，但在小咬块情况下，唇间开口减小；(c)在少数情况下，闭唇动作的持续时间有所增加，但这些时间很小，而且不一致。研究结果讨论了相对于可能的组织系统，将产生观察到的语音发音者之间的相互作用。
Inferior-superior displacements of the upper lip, lower lip, and jaw were transduced with a strain-gauge system in 4 normal-speaking adults. Movements of the upper and lower lips were compared across conditions in which the jaw was free to move and when bite blocks were used to fix the jaw at four different vertical positions. As jaw-open position was increased with the bite blocks, it was found that: (a) Positions of both lips changed for bilabial closure, but the closing movements did not usually maintain consistent proportions between lips across different bite-block sizes;(b) although the lips maintained fairly consistent maximum interlabial opening across many conditions, this opening was reduced in the small bite-block conditions; and (c) in a few cases there was an increase in the duration of lip-closing movements, but these were small and inconsistent. The findings are discussed relative to possible organizational systems that would produce the observed interactions among speech articulators.
