DESCRIPTION: The broad goal of the proposed research is development and commercialization of a multilevel model-based speech discrimination testing system designed for individuals experiencing speech discrimination difficulties ranging from mild to severe. Development of the testing system benefits from related research conducted over a 10-year period which resulted in a prototypic speech discrimination test for persons with severe to profound hearing losses. In the proposed work, we seek to increase the difficulty of the discrimination tasks and decrease test administration time. We perform detailed item, reliability and validity analyses to establish the empirical foundation fro a computerized, adaptive testing system responsive to the individual differences which exist among persons receiving audiological services. The test materials consist of sentence-level utterances presented to subjects with and without background noise. Fifty subjects will participate in the study. The testing system will be evaluated in terms of established psychometric criteria, and also for goodness-of-fit to a mathematical model for person measurement. This research represents and interdisciplinary collaboration. It is technically sophisticated in terms of current audiological practice, and has significant advantages over conventional methods of speech discrimination testing.

描述：拟议研究的广泛目标是发展和 基于多级模型的语音歧视测试的商业化 为遇到语音歧视困难的个人设计的系统 从轻度到重度不等。测试系统的开发受益于 在10年内进行的相关研究导致了原型 对严重至严重听力损失的人的语音歧视测试。 在拟议的工作中，我们试图增加歧视的困难 任务并减少测试时间。我们执行详细项目， 可靠性和有效性分析以建立经验基础。 计算机化的自适应测试系统对个体差异有反应 在接受听力服务的人中存在的。测试材料 由句子级的话语组成 背景噪音。五十名受试者将参加这项研究。测试 系统将根据既定的心理测量标准进行评估，并且 还适合对人测量的数学模型的拟合度。这 研究代表和跨学科的合作。从技术上讲 从当前的听力学实践中精致，具有重要的 比传统的语音歧视测试方法的优势。
