项目摘要

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.

项目概要获得高质量的听觉输入对于听力损失的成功言语和语言发展至关重要。由听觉神经病 (AN) 或耳蜗听力损失 (C-HL) 引起的听觉信号会降低，但在考虑到可听度后，患有 C-HL 的听众通常会表现出正常或接近正常的时间性。许多患有 AN 的听众表现出较差的时间分辨率。这很重要，因为听众对时间和频率提示的访问差异可能会影响对支持语言习得和语音感知的声学语音线索。将评估频谱和时间分辨率下降对语音的短期和长期影响与听力正常的儿童相比，AN 和 C-HL 儿童的感知和语音意识。评估将涉及频谱和时间分辨率以及言语感知的心理物理测试识别依赖于元音或辅音感知的单词。研究金提案包括研究设计、信号检测、语音领域的技能发展感知、语言发展、统计模型、专业网络发展和道德行为北卡罗来纳大学和男孩镇国家研究中心的综合资源。医院除了无与伦比的条件外，还提供独特的技术培训和职业发展机会临床和研究工作成功整合的模型。
