設計一種基于AT89C52的語音錄放系統，利用單片機、ISD2560語音錄放器件、麥克風、揚聲器等元器件實現硬件電路的設計，并利用C51高級語言設計ISD2560器件控制字的寫入和定時中斷程序。經軟硬件調試，結果表明該系統錄放效果良好，具有一定的工程實用價值。
Abstract:
Voice recording and playback system based on AT89C52is 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 ISD2560control words and timing interrupt procedures are designed by C51advanced language.Through the hardware and software test,voice recording and playback system play better voice,and this system has some engineering practical values.
