摘要

语音增强和噪声预处理算法的最新进展极大地提高了语音信号的质量和可理解性，无论是在存在噪声的环境中还是在良性环境中。将语音增强技术与语音编码算法相结合应用于政府无线通信系统是一个重要的应用领域。本文将首先介绍一个这样的系统，即2.4 kbps的美国政府军事标准混合激励线性预测(MELP)语音编码算法与AT&T研究实验室开发的语音增强算法相结合。接下来，本文对试验条件和结果进行了讨论，并对这些结果进行了解释。最后，对相关问题进行了一般性讨论并得出结论。

Speech enhancement and coding in harsh acoustic noise environments

Recent advances in speech enhancement and noise pre-processing algorithms have dramatically improved the quality and intelligibility of speech signals, both in the presence of acoustic noise as well as in benign environments. The use of speech enhancement in combination with voice coding algorithms and applied to governmental wireless communications systems is an important application area. This paper will first introduce one such system, the 2.4 kbps US Government Military Standard mixed excitation linear prediction (MELP) speech coding algorithm coupled with a speech enhancement algorithm developed by AT&T Research Labs. Next, the paper presents a discussion of the test conditions and results, and provide an interpretation of these results. Finally, a general discussion of related issues and conclusions is presented.
