基于ISD4004的智能教师点名器设计

摘要

提出用AT89S51单片机和ISD4004语音芯片设计智能教师点名器的方案.系统可以自动按序点名,还可以按需要随机点名.完成了系统的硬件电路设计和软件编程.系统克服了人工点名繁琐的缺点,具有功能实用,价格低的特点.%A scheme of smart teachers roll call based on AT89S51 and ISD4004 was proposed. The system can automatically sequence name, random name if necessary. The hardware circuit and software programming are finished. The system is functional and practical, low price to overcome the artificial named tedious disadvantage.
