SPEECH PROCESSORS FOR AUDITORY PROSTHESES

承包商应尽最大努力设计、开发和 评价语音处理器在植入听觉假体中的应用 聋人。所有听觉假体的一个重要组成部分是 语音处理器，其功能是将宽带电信号转换成 来自麦克风的信号到信息压缩信号或一组 用于驱动单个植入物刺激器的信号 以优化植入用户的语音识别方式。这个 承包商将继续努力开发基于实验室的可穿戴设备 语音处理系统；他们将设计、评估和提炼语音 利用先前植入的人体受试者的处理技术 听觉假体.确定最相关的处理因素 不同信噪比环境下的语音理解 级别，并使用此功能开发新的语音处理策略 信息。他们还将研究学习的效果通过使用 开发的可穿戴处理器在先前植入的患者中超过 延长了测试期。此外，新的测试材料将被 为更有效地评估聋人的语音处理器而开发的 植入听觉假体的人类。

The Contractor shall exert its best efforts to design, develop, and evaluate speech processors for use with implanted auditory prostheses in deaf humans. An essential component of all auditory prostheses is the speech processor whose function it is to convert the wideband electrical signal from the microphone to an information condensed signal or set of signals for driving the individual electrical implant stimulators in a manner to optimize speech recognition by the implant users. The Contractor will continue efforts to develop laboratory based and wearable speech processing systems; they will devise, evaluate, and refine speech processing techniques using human subjects with previously implanted auditory prostheses; determine processing factors which best relate to speech comprehension in environments with different signal to noise levels, and develop new speech processing strategies using this information. They will also study the effects of learning by using the developed wearable processors in previously implanted patients over an extended testing period. In addition, new test materials will be developed for more effective evaluation of the speech processors in deaf humans with implanted auditory prostheses.
