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 is to convert the wideban 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 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.

承包商应尽最大努力设计、开发和 评估与植入听觉假体一起使用的语音处理器 在聋哑人身上。 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为 从麦克风发出的信号到信息压缩信号或一组 用于驱动单个电植入刺激器的信号 优化植入物用户的语音识别的方式。 这 承包商将继续努力开发基于实验室和 与语音最相关的可穿戴语音处理因素 在具有不同信噪比水平的环境中的理解，以及 使用这些信息开发新的语音处理策略。 他们 还将研究使用开发的可穿戴设备进行学习的效果 经过长期测试，处理器已植入先前植入的患者体内 时期。 此外，还将开发新的测试材料以用于更多 对聋哑人的语音处理器进行有效评估 植入听觉假体。
