This system is made up of hardware and software, among them, the part of the hardware includes single chip 8051, voice chip ISD4004,clock chip DS1302,Matrix keyboard, LM386 audio-frequency amplifier, MIC, the- loudspeaker and some relevant peripheral circuits. And the part of the software is mainly to design some programs according to the characteristics of single chip8051d,ISD4004 and DS1302. Function that the part of the hardware realizes: Firstly，we should record the voice signal by using the stay body condenser ,then the signal will be emitted through the loudspeaker after having been enlarged by the circuit of the audio frequency ,and all these are controlled under the single chip 8051.  Function that the part of the software realizes: The single chip will control the order to pass to ISD4004 and DS1302 and the interrupt output of ISD4004 and DS1302 at the same time . Keywords：ISD40
