DESCRIPTION (provided by applicant): The study of mechanisms used for speech perception will be continued using a number of auditory phenomena and procedures developed in the principal investigator's laboratory (which include verbal transformations, phonemic restorations, spectral restoration, vowel conversions, and phonemic splitting). The aim is to examine linguistic mechanisms not readily accessible through other means. It is anticipated that the information obtained will be of help in elucidating mechanisms associated with the coding, processing, storage and retrieval of information necessary for the comprehension of speech, and should aid in understanding the etiology of dysphasias and aphasias, as well as enhancing the diagnoses and treatment of these disorders. In order to design multichannel cochlear implants that can restore hearing in deaf individuals and permit them to comprehend speech, it is necessary to have accurate data describing the information content of different spectral regions, and how they interact when combined. The principal investigator's laboratory has developed a procedure capable of obtaining such data directly, which if this application is funded, will be gathered and used to evaluate, and provide an alternative to the estimates derived from the indirect procedures in current use.

描述（由申请人提供）：将继续使用许多听觉现象和主要研究者实验室中开发的多种听觉现象和程序（包括口头转换，音素修复，光谱恢复，元音转换和语音散布）。目的是检查语言机制不容易通过其他方式访问。可以预料，获得的信息将有助于阐明与理解语音所必需的信息相关的机制，并应有助于理解不适的病因和失败的病因，并增强这些疾病的诊断和治疗。为了设计可以恢复聋人听力并允许他们理解语音的多通道人耳蜗植入物，有必要拥有准确的数据来描述不同光谱区域的信息内容，以及它们在合并时如何相互作用。首席研究者的实验室已经开发了一种能够直接获得此类数据的程序，如果资助此应用程序，将收集并用于评估该数据，并为当前使用中间接程序得出的估计值提供了替代方案。
