在三个实验中，我们证明了对颌骨扰动的反应的发音模式是特定于所产生的话语的。在实验1和实验2中，在第一次扰动实验中，在发音/Baeb/的最后/b/闭合时，在上颌运动中施加意外的恒定力载荷(5.88N)，几乎立即显示上下嘴唇的补偿，而不是舌头的补偿。同样的干扰在发声/Baez/时引起舌肌活动迅速增加，但没有主动的嘴唇补偿。虽然下巴扰动对两种发音都是一种威胁，但没有出现明显的语音失真。在实验3中，在双唇辅音的产生过程中，颌骨扰动的相位发生了变化。只有在闭合运动阶段下巴受到干扰时，才能观察到上嘴唇的远程反应。这些发现为灵活组合并列结构在言语产生中的应用提供了证据。
In three experiments we show that articulatory patterns in response to jaw perturbations are specific to the utterance produced. In Experiments 1 and 2, an unexpected constant force load (5.88 N) applied during upward jaw motion for final /b/ closure in the utterance /baeb/ revealed nearly immediate compensation in upper and lower lips, but not the tongue, on the first perturbation trial. The same perturbation applied during the utterance /baez/ evoked rapid and increased tongue-muscle activity for /z/ frication, but no active lip compensation. Although jaw perturbation represented a threat to both utterances, no perceptible distortion of speech occurred. In Experiment 3, the phase of the jaw perturbation was varied during the production of bilabial consonants. Remote reactions in the upper lip were observed only when the jaw was perturbed during the closing phase of motion. These findings provide evidence for flexibly assembled coordinative structures in speech production.
