DESCRIPTION (provided by applicant): The long-term goals of this translational project are to develop a set of multimodal tests of sentence recognition and to collect normative data from adults and children. Under natural conditions, listeners use both auditory and visual speech cues to extract meaning from speech signals containing many sources of variability. However, traditional clinical tests of spoken word recognition (SWR) routinely employ isolated words or sentences produced by a single talker in an auditory-only presentation format. The more central cognitive processes used during multimodal integration, perceptual normalization and lexical discrimination that may contribute to individual variations in SWR performance are not assessed in conventional tests of this kind. The new multimodal sentence tests will be based on paradigms and theoretical models borrowed from the field of Psychological Sciences. The research will encompass five milestones. Milestone 1. Construct two multimodal sentence tests (adult and child versions). Lexical characteristics of the sentences will be carefully controlled following the assumptions of a current model of SWR. Milestone 2. Create audiovisually-recorded, multi-talker versions of the sentence sets. Pilot data will be used to create multi- talker sentence lists that are equivalent within a given presentation format (auditory-only [A-only], visual-only [V-only or auditory plus visual [AV]). Milestone 3. Verify reliability and establish validity of the sentence sets. This will be done in a sample of adults and children with hearing loss. Milestone 4. Collect normative data concerning performance in the A, V, and AV presentation formats. Data obtained from adults and children will be analyzed separately as a function of degree of hearing status (normal, and mild, moderate, severe, or profound hearing loss in the better hearing ear) and type of sensory aid (hearing aid or cochlear implant). Milestone 5. Distribute Test Materials. The test packets will consist of DVDs containing the multimodal sentence lists as well as an instruction booklet, data gathering forms and a manual for data interpretation. These new sentence tests should provide important insights into the SWR differences and enormous variability noted among individuals with hearing loss and lead to better diagnosis, evaluation and assessment paradigms. Information obtained from these new measures should prove useful in selecting sensory aids and in developing intervention programs that are targeted to an individual's specific needs.

描述（由申请人提供）：该翻译项目的长期目标是开发一组句子识别的多模式测试，并从成人和儿童那里收集规范性数据。在自然条件下，听众同时使用听觉和视觉语音提示从包含许多可变性来源的语音信号中提取含义。但是，传统的口语识别临床测试（SWR）通常采用单个说话者在仅听觉演示格式中产生的孤立单词或句子。在多模式整合，感知归一化和词汇歧视过程中使用的更中心的认知过程可能会导致SWR性能的个体变化。新的多模式句子测试将基于从心理科学领域借来的范式和理论模型。该研究将涵盖五个里程碑。里程碑1。构建两个多模式句子测试（成人和儿童版本）。句子的词汇特征将按照当前SWR模型的假设仔细控制。里程碑2。创建句子集的录音，多词器版本。试验数据将用于创建在给定的演示格式中等效的多说话者句子列表（仅听觉[仅A-仅A]，仅视觉[仅V-horly [仅V-horly或听觉加上Visual [av]）。里程碑3。验证可靠性并确定句子集的有效性。这将在有听力损失的成年人和儿童样本中完成。里程碑4。在A，V和AV演示格式中收集有关性能的规范数据。从成人和儿童获得的数据将分别分析，这是听力状态程度（正常，轻度，中度，严重或严重的听力损失）和感觉辅助类型（助听器或耳蜗植入物）的类型。里程碑5。分发测试材料。测试数据包将由包含多模式句子列表的DVD以及指令手册，数据收集表格和用于数据解释的手册。这些新的句子测试应提供有关SWR差异的重要见解和听力损失的个体中引起的巨大变异性，并导致更好的诊断，评估和评估范例。从这些新措施中获得的信息应被证明在选择感官辅助工具和开发针对个人特定需求的干预计划中很有用。
