机载环境下的语音命令识别系统的实现

The Realization of Speech Recognition System for Airborne Avionics

信息科学的发展对电子设备的技术水平提出了更高的要求,语音识别系统将是车载、机载综合电子设备中一项不可缺少的内容。本文从实际需求出发,力求找到一种适宜于小平台机载环境下的语音识别及相关算法,构建面向实际应用的基于DSP的机载高速、高可靠性音频处理硬件平台。

With the development of information technology, there is an improving demand for the electronic facilities, and the speech -recognition system will become an inevitable part for the integrated electronic systems applied in the vehicles and airplanes. Based on the practice, this paper is focused on the realization of speech recognition and its algorithms adapted to the smaller platform for the airborne avionics. Moreover, the aim isto consti＇uct a DSP - based audio hardware platform to the reality which has the properties of high - speed and high - reliability.
