本研究探讨了言语-语言病理学家（SLP）对构音障碍患者言语清晰度的估计的可靠性和有效性，包括视觉模拟量表（VAS）方法和临床常用的百分比估计方法。来自20名具有不同病因的构音障碍的说话者的语音样本被用于收集来自天真听众的正字法transmittance和VAS评级以及来自SLP的可懂度的百分比估计。两个SLP可懂度措施的评价者内和评价者间的可靠性进行了评估，这些措施之间的关系进行了评估。最后，线性回归被用来评估天真的听众的正字法转录分数和两个SLP可懂度测量之间的关系。结果表明，两个SLP可懂度测量的评价者内信度都很强，SLP等级之间的评价者间信度为中等至优秀。还观察到SLP的VAS评分和百分比估计值之间存在中度正相关关系。最后，SLP的百分比估计和VAS评分都能预测幼稚听众的正字法转录分数，其中SLP的百分比估计是最强的预测因子。总之，平均SLP百分比估计和VAS评级是有效和可靠的可懂度测量。然而，这些措施的有效性和可靠性不同的SLP。
This study examined the reliability and validity of speech-language pathologists’ (SLP) estimations of speech intelligibility in dysarthria, including a visual analog scale (VAS) method and a percent estimation method commonly used in clinical settings. Speech samples from 20 speakers with dysarthria of varying etiologies were used to collect orthographic transcriptions from naïve listeners and VAS ratings and percent estimations of intelligibility from SLPs . Intra- and interrater reliability for the two SLP intelligibility measures were evaluated, and the relationship between these measures was assessed. Finally, linear regression was used to evaluate the relationship between the naïve listeners’ orthographic transcription scores and the two SLP intelligibility measures. The results indicated that the intrarater reliability for both SLP intelligibility measures was strong, and the interrater reliability between the SLP ratings was moderate to excellent. A moderate positive relationship between SLPs’ VAS ratings and percent estimations was also observed. Finally, both SLPs’ percent estimations and VAS ratings were predictive of naïve listeners’ orthographic transcription scores, with SLPs’ percent estimations being the strongest predictor. In conclusion, the average SLP percent estimations and VAS ratings are valid and reliable intelligibility measures. However, the validity and reliability of these measures vary between SLPs.
