The articulatory gestures of the velum in two Wernicke aphasic patients were examined to compare their performances with those of an apraxic patient by means of the fiberoptic technique. In contrast to the marked variability in the apraxic performance in terms of velum height and segmental duration, the two fluent aphasic subjects showed a relatively high degree of consistency in velar movements throughout several repetitions of nonsense syllables and meaningful words. In addition, both patients exhibited a normal pattern of anticipatory coarticulation. Analyses of the velar movement patterns during the speech-sound error processes of both patients suggested that these errors were not due to an impairment at the level of articulatory programming but to an error in the selection of a target phoneme.
通过光纤技术检查了两名韦尼克失语症患者软腭的发音姿势，以便将他们的表现与一名失用症患者的表现进行比较。与失用症患者在软腭高度和音段时长方面表现出的明显变异性不同，这两名流利性失语症患者在重复无意义音节和有意义单词的过程中，软腭运动表现出相对较高的一致性。此外，两名患者都表现出正常的预期协同发音模式。对两名患者语音错误过程中软腭运动模式的分析表明，这些错误并非由于发音程序层面的损伤，而是由于目标音素选择错误。
