An Exploration of Listener Variability in Intelligibility Judgments
McHenry, Monica
American Journal of Speech-Language Pathology, v20 n2 p119-123 May 2011
Purpose: This study was designed to assess potential contributors to listener variability in judgments of intelligibility. Method: A total of 228 unfamiliar everyday listeners judged speech samples from 3 individuals with dysarthria. Samples were the single-word phonetic contrast test, the Sentence Intelligibility Test, an unpredictable sentence intelligibility test, and conversational speech. Results: Across speakers, significant variability was found for all samples except the phonetic contrast test. Across tasks, significant variability was found for all speakers. There were no significant differences in age, gender, or education between the highest and lowest scoring listeners on the phonetic contrast test. Conclusions: These findings suggest that seemingly objective intelligibility tests are subject to a number of factors that affect scores. (Contains 3 tables.)
