摘　　要：为解决强背景噪声下的语音通信问题,设计了基于ARM核处理器的硬件控制平台和以DSP为核心的语音处理系统,采用嵌入式以太网完成实时语音和指令数据的传输;在uClinux嵌入式操作系统下开发了外部设备的驱动程序和网络应用程序,系统在实际应用中满足了语音实时通讯要求。A speech signal processing system based on the hardware control platform of ARM core processor and DSP is designed to resolve the speech communication in the high noise environment, transmission of real time speech and instrument datum is realized by the embedded ethernet. Device driver and network application program are developed in uClinux embedded operating systems. Result shows this system has met the real time demands of speech communication.
