DESCRIPTION (provided by applicant): Despite that speech is often characterized by either spectral or temporal cues, its everyday perception involves the integration of temporal patterns present at different spectral loci. The long-term goals of the proposed research program are to further our understanding of the normal mechanisms employed during the processing of the spectro-temporal patterns in speech, and to characterize limitations that hearing impairment places on these mechanisms. Techniques combining psychoacoustic and speech perception research will be employed to extend a number of recent observations concerning spectro-temporal processing. These examinations will involve both listeners with normal hearing and those with sensorineural hearing impairment. The aims are: (1) To establish the spectral resolution employed to process speech (2) To examine the use of temporal information at different rates and spectral frequencies (3) To examine the spectro-temporal processing deficit in hearing impaired listeners The information gained has the ability to further our understanding of normal speech processing. It also has the ability to further our understanding of the impact of hearing impairment by providing a comprehensive examination of the ability to use the fluctuating temporal patterns in speech, and by examining the influence of broadened auditory tuning on the reception of particular speech materials in particular frequency regions.

描述(申请人提供)：尽管语音的特征通常是光谱或时间线索，但它的日常感知涉及不同光谱位置的时间模式的整合。这项拟议研究的长期目标是加深我们对语音频谱-时间模式处理过程中正常机制的理解，并表征听力障碍对这些机制的限制。结合心理声学和语音感知研究的技术将被用来扩展最近关于谱-时间处理的一些观察结果。这些检查将包括听力正常的听者和感觉神经性听力障碍的听者。其目的是：(1)建立用于处理语音的频谱分辨率；(2)考察在不同速率和频谱频率下使用时间信息的情况；(3)考察听障听者的频谱-时间处理缺陷。所获得的信息能够加深我们对正常语音处理的理解。它还能够通过全面检查在语音中使用波动的时间模式的能力，以及通过检查扩大的听觉调谐对特定频率区域中特定语音材料的接收的影响，来加深我们对听力障碍影响的理解。
