项目摘要

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(由申请人提供):尽管语音通常以频谱或时间线索为特征,但其日常感知涉及不同频谱位点处存在的时间模式的整合。拟议的研究计划的长期目标是进一步了解语音中的频谱-时间模式处理过程中采用的正常机制,并描述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一些最近的观察有关频谱时间处理。这些检查将涉及听力正常和感音神经性听力障碍的听众。其目标是:(1)建立用于处理语音的频谱分辨率(2)检查在不同速率和频谱频率下时间信息的使用(3)检查听力受损的听者的频谱-时间处理缺陷所获得的信息能够进一步加深我们对正常语音处理的理解。它也有能力进一步我们的理解听力障碍的影响,通过提供一个全面的考试的能力,使用波动的时间模式的讲话,并通过检查的影响,扩大听觉调谐的接收特定的语音材料在特定的频率区域。
