Although we would expect that the role of visible speech in multimodal speech perception would have the greatest relevance to individuals with hearing impairment, relatively few analytic studies have been done with these participants. Their adequate understanding of spoken language usually requires information from several modalities or other sources of information. The framework of the fuzzy logical model of perception (FLMP) is used to assess how individuals with hearing impairment evaluate and integrate multiple sources of information. Given this framework, a distinction can be made between information and information processing. Within this framework, we can ask what information differences and information-processing differences exist among individuals with normal hearing and those with hearing impairment. Four experimental studies from the literature are analyzed to address these questions. Test items are presented under both unimodal and bimodal conditions. Of central interest is the nature of the bimodal performance as a function of the unimodal performance. The findings show that, although information differences obviously exist across different populations, their information processing involved in pattern recognition appears to be the same and is well described by the FLMP.
虽然我们预计可见语音在多模态语音感知中的作用与听力障碍者最为相关，但针对这些参与者进行的分析研究相对较少。他们对口语的充分理解通常需要来自多种模态或其他信息源的信息。感知模糊逻辑模型（FLMP）框架用于评估听力障碍者如何评估和整合多种信息源。基于这个框架，可以区分信息和信息处理。在这个框架内，我们可以询问听力正常者和听力障碍者之间存在哪些信息差异和信息处理差异。分析了文献中的四项实验研究来解决这些问题。测试项目在单模态和双模态条件下呈现。核心关注点是双模态表现作为单模态表现的函数的性质。研究结果表明，虽然不同人群之间显然存在信息差异，但他们在模式识别中涉及的信息处理似乎是相同的，并且FLMP能很好地描述这一点。
