So,this design is a small try to solve such problem, combined with cost, application environment conditions for limits, design with the single chip processor as calling device portable speech.The product must meet the user can easily around the method of help inform people, immediately understand the parties to happen, and timely response requirements.Take it for a brief,the design of the portable speech calling device is just for this purpose, which can let us better solve once emergencies, which will reduce the damage to a minimum. This paper mainly recommends a system based on the brief of CPUs controlling about APR9600PY,which is for C coding and is based on STC89C52RC.For convenience , we pur the APR9600 voice chip into a recording module and prerecorded the useful voice signal.Then put the record chip to the design of the overall circuit to work.We make the chip up to a port,and control the working mode through the MCU program within its.We put the 1602LCD in SCM common external interface to
