摘　　要：设计一种基于AT89C52的语音录放系统,利用单片机、ISD2560语音录放器件、麦克风、扬声器等元器件实现硬件电路的设计,并利用C51高级语言设计ISD2560器件控制字的写入和定时中断程序。经软硬件调试,结果表明该系统录放效果良好,具有一定的工程实用价值。Voice recording and playback system based on AT89C52 is designed in this paper.Using the single-chip microcomputer,voice recording and playback chip ISD2560,microphone and speaker to realize the hardware circuit design. Writing ISD2560 control words and timing interrupt procedures are designed by CS1 advanced language.Through the hardware and software test, voice recording and playback system play better voice, and this system has some engineering practical values.

关 键 词：AT89C52 ISD2560 定时中断 语音录放
