18名听力正常的大学生在一个类似英语的语音环境中对声母和韵母的视觉知觉进行了测试，测试了英语辅音的同质性。多项选择可理解性测试提供了刺激项目，但提供了特殊的反应表，以允许每个受试者对被判断为与刺激项目相似或同源的任何辅音做出可能的反应。删除了尽可能正确的回答，以提供可用数量的混淆。即使在任务完成后，受试者也没有意识到正确回答的删除。对产生的混淆矩阵进行分析，找出辅音之间的显著混淆；这些混淆被分成相互排斥的术语视位。这些结果倾向于支持之前发表的同音语音的语言分组，而不是演讲稿阅读方法开发者的经典列表。与前者的不同之处在于增加了最小的语音冗余。
Eighteen college students with normal hearing responded to the visual perception of initial and final consonants in an English-like phonetic environment in a test of the homopheny of consonant sounds of English. The Multiple-choice Intelligibility Test provided stimulus items but special response sheets were provided to allow each subject a possible response of any consonant judged homotypical or homorganic to the stimulus item. Correct answers as possible responses were deleted to provide a usable number of confusions. Subjects were not aware of the deletion of correct responses even after the task was completed. Resulting confusion matrices were analyzed for significant confusions among consonants; these confusions were grouped into mutually exclusive classes termedvisemes. The results tend to support previously published linguistic groupings of homophenous sounds rather than the classical listing from the developers of speechreading methodology. Variations from the former are explained in terms of the addition of minimal phonetic redundancy.
