96名听力正常的成年人在2天内观看了三种类型的记录语音阅读材料（辅音-元音无意义音节，孤立的单词和句子）。对无意义音节的反应进行了正确的音节和正确的音节组的评分;对单词和句子的反应进行了正确的单词，正确的音素，以及刺激和反应之间的视觉距离的估计。概化分析被用来量化性能变异的来源。受试者和测试项目的变异性的重要来源，为所有三种类型的材料;影响的谈话者和测试的一天各不相同，但相对较小。对于每种类型的材料，替代模型的测试建设和测试成绩的解释进行了评估，通过估计的概化系数作为测试长度的函数。无意义音节的表现与单词和句子的相关性约为0.50，而单词和句子之间的相关性通常超过0.80。
Ninety-six adults with normal hearing viewed three types of recorded speechreading materials (consonant-vowel nonsense syllables, isolated words, and sentences) on 2 days. Responses to nonsense syllables were scored for syllables correct and syllable groups correct; responses to words and sentences were scored in terms of words correct, phonemes correct, and an estimate of visual distance between the stimulus and the response. Generalizability analysis was used to quantify sources of variability in performance. Subjects and test items were important sources of variability for all three types of materials; effects of talker and day of testing varied but were comparatively small. For each type of material, alternative models of test construction and test-score interpretation were evaluated through estimation of generalizability coefficients as a function of test length. Performance on nonsense syllables correlated about .50 with both word and sentence measures, whereas correlations between words and sentences typically exceeded .80.
