信息科学的发展对指挥控制的技术提出更高的要求，语音识别将是车载、机载、舰载综合电子设备中一项不可缺少的内容。但海、陆、空等指挥控制环境中高噪声的存在及其导致的话者语音变化，为语音识别系统的可靠应用带来了困难，要解决这个问题，就必须研制具有抗噪声能力的语音识别系统。本文基于语音识别的基本原理，通过对噪声特性及其对语音识别影响的分析，从提高系统的鲁棒性入手，探讨了抗噪声语音实时识别系统
The development of information science puts forward higher requirements on the technology of command and control, and speech recognition will be an indispensable element in the on-board, airborne and carrier-based integrated electronic equipment. However, the existence of high noise in the command and control environment such as the sea, land and air and the voice changes caused by the speaker voice bring difficulties to the reliable application of the voice recognition system. To solve this problem, it is necessary to develop a voice recognition system with anti-noise ability . Based on the basic principle of speech recognition, through the analysis of noise characteristics and its impact on speech recognition, starting from improving the robustness of the system, this paper discusses the anti-noise speech real-time recognition system
