Currently, speech synthesis, speech recognition, voice storage and playback technology more widely, despite the use of single-chip measurement and control system in general have a hardware circuit ¬ (such as A/D, D/A, memory, etc.) can completion of the digital speech signal processing, but a single function, and the effect is not very good. In this paper, AT89C52 single-chip component and the voice chip ISD2560 voice storage system, the sub-taking voice, combined playback, combined with liquid crystal display LCD module OCMJ2X8, can be a simple function of the bus stop. A simple hardware circuit, debugging convenience, cost-effective, practical. Keywords: voice recording system single-chip microcomputer AT89C52 ISD2560
