摘 要语音集成电路的出现是传统语音录放设备的革新，最近几年深受人们的欢迎，并得到迅猛的进展。相对于传统的录音方式，它只需很少的电子器件，就能实现录放功能，可以永久保存数据。目前，在国外，语音录放电路已经得到广泛的应用，在国内，语音录放应用电路的高潮正在逐步形成。在我们的日常生活中，语音存储回放技术得到了广泛的应用，诸如公交车报站器，采访笔，MP3 播放器，电话语音自动转接留言等，使得产品的功能强大，逐步淘汰了磁带录音的传统方式，方便了人们的生活，推动了社会进步。本论文基于 AT89S52 单片机与 ISD4004 语音录放芯片为主要部件，通过硬件与软件的设计实现语音录放的功能。系统硬件电路设计简单，方便调试，价格便宜，有用性强。关键词：语音录放系统；单片机 AT89S52；ISD4004AbstractVoice integrated circuit is the traditional voice recording equipment innovation, in recent years welcomed by the people, and get rapid development. Compared with the traditional recording methods, it requires little electronic devices can achieve recording function, you can permanently store data .At present, foreign, voice recording circuit has been widely used in the country, the climax of voice recording application circuit is gradually taking shape. In our daily life, voice storage playback technology get in a wide range of applications, such as the bus stop, and an interview with recorder, MP3 player, telephone voice messages and other automatic switching, allowing for powerful, out of the tape recording the traditional way to facilitate people's lives, and promote social progress. This paper based on AT89S52 MCU and ISD4004 voice recording chips as the main component, voice recording functionality through hardware and software design. System hardware circuit design is simple, easy to debug, cheap and practical.Keywords: Voice recording systems；AT89S52 MCU；ISD4004目 录1 绪论...............................................................11.1...
