概化理论（Cronbach，Gleser，Nanda，& Rajaratnam，1972）被用来估计由三个来源的语音阅读句子的变异解释的百分比：主题，说话者，和句子材料。100 CID日常句子（戴维斯和西尔弗曼，1970年），由一名男性和一名女性说话的视频光盘录音，呈现给104名听力正常的受试者。对于单个句子的表现（正确的单词总数），最重要的系统性变异来源是句子（26.3%），语音阅读器（10.5%），说话者（4.9%），以及说话者和句子的相互作用（5.1%）。剩余误差占总方差的51.2%。概化功能，作为测试长度的函数，五种模式的测试管理和解释。对于10项、50项和100项的列表，对于单个谈话者，预测的概括性分别为0.70、0.92和0.96。这些录音的CID句子的心理特征也被提出。
Generalizability theory (Cronbach, Gleser, Nanda, & Rajaratnam, 1972) was used to estimate the percentage of variance explained by three sources of variability in speechreading sentences: the subject, the talker, and the sentence materials. Videodisc recordings of the 100 CID Everyday Sentences (Davis & Silverman, 1970), spoken by a male and a female talker, were presented to 104 subjects with normal hearing. For performance on individual sentences (total number of words correct), the most important systematic sources of variability were the sentence (26.3%), the speechreader (10.5%), the talker (4.9%), and the interaction of talker and sentence (5.1%). Residual error accounted for 51.2% of the variance. Generalizability functions are presented, as a function of test length, for five models of test administration and interpretation. For 10-, 50-, and 100-item lists, generalizability is predicted to be .70, .92, and .96, respectively, for a single talker. Psychometric characteristics of these recordings of the CID sentences are also presented.
