In this study, the speech of a 28-year-old male with acquired brain injury and who presents with an undefined neuromotor speech disorder which cannot be categorised as either apraxia of speech or dysarthria, is described. Voice onset time, vowel duration, utterance duration and vowel formant analyses were done acoustically. A perceptual analysis and intelligibility rating were also executed. The subject was found to present with unique perceptual symptoms, intelligible speech, prolonged sound duration and distorted vowel quality. The results are interpreted within the context of the Four Level Framework of Speech Sensorimotor Control (Van der Merwe, 1997).
在本研究中，描述了一名28岁男性后天性脑损伤患者的言语情况，该患者存在一种无法归类为言语失用症或构音障碍的不明神经运动性言语障碍。通过声学方法进行了嗓音起始时间、元音时长、话语时长和元音共振峰分析。还进行了感知分析和可懂度评级。发现该受试者存在独特的感知症状、可懂言语、延长的声音时长和扭曲的元音质量。研究结果在言语感觉运动控制四级框架（范德默韦，1997年）的背景下进行了解释。
