Indices of interjudge reliability and inter- and intrajudge agreement were calculated from the ratings made by 15 experienced speech clinicians on five deviant speech dimensions with respect to 15 speakers with ataxic dysarthria. Speakers were chosen to cover a wide range of speech intelligibility (16-97%) as measured by the sentence intelligibility transcriptions of the Assessment of Intelligibility of Dysarthric Speech (Yorkston & Beukelman, 1981). Intraclass correlation coefficients derived from each judge on two occasions were above .6 for imprecise consonants, excess and equal stress, and harsh voice, but below .6 for distorted vowels and below .5 for irregular articulatory breakdown. The last dimension also had the lowest percent agreement for the interjudge and intrajudge comparisons. Poor speech dimension definition seems to be the most likely source of error on irregular articulatory breakdown. Judges agreed equally well in rating dysarthric speech across the range from low to high intelligibility.
根据15位经验丰富的言语临床医生对15名共济失调型构音障碍患者的五个异常言语维度的评分，计算了评判者间信度以及评判者间和评判者内一致性的指标。通过构音障碍言语可懂度评估（Yorkston & Beukelman，1981）的句子可懂度转录测量，选择的患者涵盖了广泛的言语可懂度范围（16%-97%）。每位评判者在两个不同时间得出的组内相关系数，对于不清晰辅音、重音过多和平等重音以及粗糙嗓音而言，均高于0.6，但对于扭曲元音低于0.6，对于不规则发音中断低于0.5。在评判者间和评判者内比较中，最后一个维度的一致性百分比也是最低的。对于不规则发音中断，言语维度定义不佳似乎是最可能的误差来源。评判者在对从低到高可懂度范围内的构音障碍言语进行评分时，一致性程度相同。
