摘要

本文主要研究语音处理和自适应滤波。本文介绍的应用程序在LabVIEW中以在线和离线两种方式实现。在线模式程序用于创建语音记录和来自室外环境以及来自家庭的各种干扰的数据库。然后，离线应用程序用于测试语音处理需要的自适应算法。比较各个算法效率的标准主要是提高信噪比。为了测试滤除率，我们选择了一种全局信噪比方法。

Speech Signal Processing using Microphones NI 9234 and LabVIEW

The paper deals with the speech processing and adaptive filtration. Introduced application is implemented in both online and offline mode in LabVIEW. The online mode program is used to create a database of speech recordings and various interferences from the outdoor environment as well as from the home. The offline application then serves to test adaptive algorithms for the needs of speech processing. The criterion for comparing the efficiency of individual algorithms is primarily to increase the signal to noise ratio. To test the filtration rate, a global SNR method was chosen.
