本研究以听力正常和轻度听力障碍的成年人为研究对象，探讨了情境线索和推理策略对言语阅读的影响。日常言语句子（戴维斯和西尔弗曼，1968年）由一名女性说话者产生的视频没有声音的背景下的视觉场景。一个非语言的声音信号与每个句子相匹配，并被配音到录音中。因此，每个测试项目由一个听不见的句子组成，并提供了光学和声学情境线索。实验任务的结构，使受试者speechread使用演绎或归纳推理策略的句子。结果表明，更大的成功，在言语阅读时，句子与相关的情景线索相匹配时，提供无关的线索。只有在使用归纳推理时才注意到这种差异。研究结果表明，情景线索是最有用的演讲时，他可以放心，一个强大的关系之间存在的口头信息和谈话者的情景背景。
The influence of situational cues and reasoning strategies on speechreading was studied in normal-hearing and minimally hearing-impaired adults. Everyday Speech Sentences (Davis & Silverman, 1968) produced by a female talker were videotaped without sound in the context of a visual background scene. A non-verbal acoustic signal was matched to each sentence and dubbed onto the recording. Thus, each test item consisted of an inaudible sentence presented with an optical and acoustic situational cue. The experimental task was structured so that subjects speechread sentences using deductive or inductive reasoning strategies. Results demonstrated greater success in speechreading when sentences were matched with related situational cues than when unrelated cues were provided. This difference was noted only when inductive reasoning was used. The findings suggest that situational cues are most useful to the speechreader when he can be assured that a strong relationship exists between the spoken message and the talker's situational background.
