PROJECT SUMMARY Access to high-quality auditory input is crucial for successful speech and language development. Hearing losses caused by Auditory Neuropathy (AN) or Cochlear Hearing Loss (C-HL) degrade the auditory signal, but in different ways. After accounting for audibility, listeners with C-HL often exhibit normal or near-normal temporal resolution accompanied by impaired spectral resolution. Many listeners with AN display poor temporal resolution. This is important because differences in a listener’s access to timing and frequency cues can affect sensitivity to acoustic-phonetic cues that support both language acquisition and speech perception. The proposed research will evaluate the short-term and long-term effects of degraded spectral and temporal resolution on speech perception and phonological awareness in children with AN and C-HL compared to children with normal hearing. Evaluation will involve psychophysical tests of spectral and temporal resolution as well as speech perception for words in which recognition relies on either vowel or consonant perception. The training plan outlined in this fellowship proposal includes skill development in the areas of research design, signal detection, speech perception, language development, statistical modeling, professional network development, and ethical conduct of research. The combined resources of The University of North Carolina and Boys Town National Research Hospital provide unique opportunities for technical training and career development, in addition to unparalleled models of the successful integration of clinical and research endeavors.

项目摘要 访问高质量的听觉输入对于成功的语音和语言发展至关重要。听力损失 由听觉神经病（AN）或耳蜗听力损失（C-HL）引起的听觉信号，但在 不同的方式。考虑到可听性后，C-HL的听众经常暴露于正常或近正常的临时性 通过频谱分辨率受损实现的分辨率。许多听众表现出较差的临时分辨率。 这很重要，因为听众访问时间和频率提示的差异会影响对 支持语言获取和语音感知的声学线索。拟议的研究 将评估降解光谱和临时分辨率对语音的短期和长期影响 与正常听力的儿童相比，患有AN和C-HL的儿童的感知和语音意识。 评估将涉及光谱和临时分辨率的心理物理测试，以及语音感知 识别依赖元音或辅音感知的单词。其中概述了培训计划 奖学金提案包括研究设计领域，信号检测，语音的技能发展 感知，语言发展，统计建模，专业网络发展和道德行为 研究。北卡罗来纳大学和男孩镇国家研究的综合资源 医院为技术培训和职业发展提供了独特的机会，除了无与伦比 成功整合临床和研究努力的模型。
