Articulatory anticipation of vowel gestures was assessed in an apraxic patient, a dysarthric patient, and three normal speakers. The technique of assessment included perceptual identification of gated speech stimuli. The speech material consisted of /getVte/ utterances with the target vowels /i/, /y/, and /u/. In the case of the apraxic patient the gated vowels were identified at a later instant relative to the preceding plosion burst than in the normal speakers. This result was interpreted as reflecting a delayed onset of coarticulatory gestures, in particular lip rounding. The identification rates for the dysarthric's vowels rather reflected the general reduction of this patient's vowel space.
对一名失用症患者、一名构音障碍患者和三名正常说话者进行了元音手势的发音预期评估。评估技术包括对门控语音刺激的感知识别。语音材料由带有目标元音/i/、/y/和/u/的/getVte/发音组成。在失用症患者中，与正常说话者相比，门控元音在相对于前一个爆破音爆发的更晚时刻被识别出来。这一结果被解释为反映了协同发音手势的延迟开始，尤其是唇圆化。构音障碍患者元音的识别率更反映了该患者元音空间的普遍缩小。
