研究人员对 5 名神经受损受试者的下唇峰值发音速度以及上下唇之间的时间协调性进行了研究，这些受试者的言语行为符合言语失用症的诊断。比较两个嘴唇的速度和运动开始时间之间的差异，以准确和不准确地发音。还在产生音节 [pæ] 期间和非语言运动期间测量峰值发音速度。准确和不准确的单词产生在峰值发音速度或两个嘴唇的运动开始方面没有系统差异。此外，与语速相关的运动速度没有系统性变化。我们得出的结论是，一些失语者在产生高运动速度的能力方面并没有缺陷。
Peak articulatory velocity of the lower lip and temporal coordination between the upper and lower lips were studied in 5 neurologically impaired subjects with speech behaviors consistent with a diagnosis of apraxia of speech. Differences in velocity and the timing between the movement onset of the two lips were compared for accurate and inaccurate productions of words. Peak articulatory velocity also was measured during the production of the syllable [pæ] and during a nonverbal movement. There were no systematic differences across accurate and inaccurate productions of words in peak articulatory velocity or movement onsets of the two lips. Furthermore, there were no systematic changes in movement velocity related to speech rate. We conclude that some apraxic speakers do not have a defect in the ability to produce high movement velocities.
