The purpose of this study was to determine the relationship between information transfer and speech intelligibility, as measured by single-word and paragraph transcription across a wide range od dysarthric speakers. Nine dysarthric speakers, including ataxic, spastic, and hypokinetic types, participated in the study. Their performance was judged by 108 listeners. The correlations between information transfer and paragraph and transcription scores and between information transfer and word transcription scores were high, i.e., 0.95 and 0.90, respectively. Word transcription scores tended to be slightly lower than information transfer scores for mildly dysarthric speakers. Clinical implications of these findings were discussed.
本研究的目的是通过对广泛的构音障碍患者进行单字和段落转录来确定信息传递与言语清晰度之间的关系。九名构音障碍患者，包括共济失调型、痉挛型和运动减退型，参与了这项研究。他们的表现由108名听众进行评判。信息传递与段落及转录分数之间以及信息传递与单词转录分数之间的相关性很高，分别为0.95和0.90。对于轻度构音障碍患者，单词转录分数往往略低于信息传递分数。讨论了这些发现的临床意义。
