HEARING AIDS, COCHLEAR IMPLANTS AND SPEECH RECOGNITION

描述(申请人提供)：提出了三套实验，以解决与临床相关的问题，以管理听力受损的人。所获得的信息将有助于确定哪种设备(助听器、传统人工耳蜗术或短电极人工耳蜗术)最适合特定患者。该项目还将解决设备是否在向患者传输语音提示方面发挥了足够的作用的问题。具体地说，该项目将1)使用短电极人工耳蜗的模拟从正常听力的听者那里获得语音识别数据，以确定哪些类型的听力损失配置可能适合于该设备；2)从安装了人工耳蜗和助听器的听者的噪声数据中获得语音识别，以确定人工耳蜗(包括短电极和长电极)对不同程度听力损失的潜在优势或劣势；以及3)使用对感知语音的光谱和时间线索的能力的直接测试来预测助听器和人工耳蜗植入物识别语音的能力。

DESCRIPTION (provided by applicant): Three sets of experiments are proposed that address clinically-relevant questions for the management of hearing-impaired persons. The information obtained will assist in deciding which device (hearing aid, traditional cochlear implant, or short-electrode cochlear implant) is most appropriate for a particular patient. The project will also address the question of whether a device is performing adequately in the transmission of speech cues to the patient. Specifically, the project will 1) obtain speech recognition data from normal-hearing listeners using a simulation of the short-electrode cochlear implant to determine which types of hearing loss configurations might be appropriate candidates for this device; 2) to obtain speech recognition in noise data from listeners with cochlear implants and hearing aids to determine the potential advantages or disadvantages of a cochlear implant (both short- and long-electrode) for various degrees of hearing loss; and 3) to use a direct test of the ability to perceive the spectral and temporal cues of speech to predict the abilities of hearing aids and cochlear implants to recognize speech.
