摘　　要：介绍了一种基于ARM9和嵌入式Linux的智能语音记录仪的设计。硬件采用ARM微处理器,完成了语音检测电路、IIS音频电路、触摸屏和以太网接口电路的设计。建立交叉编译环境,详细阐述了音频驱动程序和应用程序的开发过程。系统可实现信号自动检测、自动录音、查询播放等多种功能。该记录仪已应用到某型战车驾驶舱内的多路喉头送话器语音记录中,具有体积小、功耗低、录音容量大、回放清晰等特点。The intelligent voice recording instrument based on ARM9 microprocessor and embedded Linux operation system was introduced. The hardware system based on ARM microprocessor including voice detection circuit, ⅡS audio circuit, touch screen panel and Ethernet interface circuit was designed. The cross-compiling software environment was set up. The development process of audio driver and application was expatiated. The system can complete multiple functions, such as signal automatic detection, automatic recording, inquiry playing etc. This recording instrument has been applied to recording multiplex neck telephone voice in the operator cabin of some chariot, and it has the characteristics Of small volume, low power consumption, big storage capacity and clear voice replay, etc.
