SPEECH PROCESSORS FOR AUDITORY PROSTHESES

承包商应尽最大努力设计、开发和 评估用于植入式听觉假体的语音处理器， 耳聋的人类 所有听觉假体的一个基本组成部分是 语音处理器，其功能是将宽带电 信号转换为信息压缩信号或一组信息压缩信号 用于驱动各个电植入刺激器的信号， 优化植入用户语音识别的方式。 的 承包商将继续努力开发基于实验室和可穿戴的 语音处理系统;他们将设计，评估和完善语音 使用先前植入了药物的人类受试者的处理技术 听觉假体;确定与下列因素最相关的处理因素： 不同信噪比环境下语音理解 水平，并开发新的语音处理策略，使用此 信息. 他们还将研究学习的效果， 在以前植入的患者中开发了可穿戴处理器， 延长测试时间。 此外，新的测试材料将 为更有效地评估聋人的语音处理器而开发 植入了听觉假体的人类

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.
