摘　　要：智能语音提示系统是一种可对语音存储进行修改的语音提示器。设计一种用51系列单片机作控制器,对ISD4004系列语音芯片进行录、放音控制的方案。该方案硬件电路部分包含单片机控制语音电路、录/放音电路;软件部分为单片机控制主程序及录放音子程序。ISD4004所有操作由控制器的操作命令通过串行通信接口(SPI)送人。The intelligent voice prompt system is one of the voice prompt equipments which has the ability of rewriting records of voice.This paper has discussed a kind of solution realizing control over voice record and playback about ISD4004 serial voice chips by using of micro control unit（MCU） of 51 serial. The hardware of the system comprises a voice control circuit with MCU as well as a circuit of voice record / playback; And the software consists of a MCU control man program and a subroutine for voice record/playback All the operations about the ISD4004 chip is input by controller operational instructions through the SPI of ISD4004 chip.
