This report presents cinefluorographic data on the articulation of isolated vowels, VCV nonsense utterances, and short sentences by five subjects with athetoid cerebral palsy. Articulatory abnormalities were identified from tracings of vocal tract shapes and from displacement-by-time plots of articulatory events. The most frequent abnormalities were large ranges of jaw movement, inappropriate positioning of the tongue for various phonetic segments (especially because of a reduced range of tongue movement in the anteroposterior dimension), intermittency of velopharyngeal closure caused by an instability of velar elevation, prolonged transition times for articulatory movements, and retrusion of the lower lip. The speech disorder associated with athetosis is considered with respect to a model of motor learning.
本报告展示了五名患有手足徐动型脑瘫患者在孤立元音、VCV无意义话语及短句发音时的动态荧光造影数据。通过声道形状的描记图以及发音事件的位移-时间图来识别发音异常。最常见的异常包括：下颌运动范围大；在不同语音段中舌位不当（尤其是由于舌在前后维度上运动范围减小）；软腭抬高不稳定导致腭咽闭合间歇性出现；发音动作的过渡时间延长；下唇后缩。结合运动学习模型对与手足徐动症相关的言语障碍进行了探讨。
