本文对32例17 ~ 55岁男性痉挛性和18例动脉状突性的言语清晰度和发音障碍进行了检查。选择是基于脑瘫的明确诊断，足够的智力，听力和执行所需任务的能力。从天真的听众那里获得了两个语音可理解性的估计：正确识别的单个单词和散文可理解性评级。采用双音位动力学（DDK）音节率和所选音位的发音正确率作为发音障碍的指标。这50名受试者在两项可理解性评估中平均被判定为50%的可理解性。组平均DDK率为2.9个音节/秒，78%的音素被正确地转录。在所有的言语测试中，痉挛受试者的平均得分都优于类人猿，即使在调整了身体残疾和智商的群体不平等后，在单字可理解性和DDK率方面也明显如此。在这个样本中，痉挛患者的身体残疾程度较低，智商也较低而不是类风湿性关节炎。脑瘫患者构音障碍的具体音位特征有：(1)舌前位置不准确；(2)擦音和模糊发音的精度降低；(3)无法实现元音发音空间的极端位置。将这些结果与脑瘫儿童报告的结果进行比较，表明辅音位置和方式问题是脑瘫构音障碍的相当稳定的特征。
The speech intelligibility and articulatory impairment of 32 spastic and 18 athetoid males, aged 17-55, were examined. Selection was based on a definite diagnosis of cerebral palsy, and adequate intelligence, hearing, and ability to perform the required tasks. Two estimates of speech intelligibility were obtained from naive listeners: single words correctly recognized and prose intelligibility rating. Diadochokinetic (DDK) syllable rates and percent correct articulation of selected phonemes were employed as indices of articulatory impairment. The 50 subjects were, on average, judged to be 50% intelligible on both intelligibility estimates. Group mean DDK rate was 2.9 syllables per second and 78% of phonemes were transcribed as correctly articulated. :The mean scores of the spastic subjects were superior to the athetoids on all speech measures, significantly so for single-word intelligibility and DDK rate even when group inequalities for physical disability and I.Q. were adjusted. In this sample, spastics were less physically disabled and had lower I.Q.'s than athetoids. Specific phonemic features characteristic of the dysarthria in cerebral-palsied subjects were: (1) anterior lingual place inaccuracy; (2) reduced precision of fricative and affricate manners; and (3) inability to achieve the extreme positions in the vowel articulatory space. A comparison of these results with those reported for children with cerebral palsy suggests that the consonantal place and manner problems are fairly stable features of cerebral palsy dysarthria.
