基于单片机语音点名系统的设计

Design of Voice Roll Call System Based on Single Chip Microcomputer

为了优化多媒体教室的上课点名时间长和教师花很大的时间和精力去点名和登记的问题,文章设计利用单片机和LD3320语音识别模块、语音播报模块和STC-USB-Driver串口模块构成简单的点名系统,将学生答“到”或“在”的声音进行识别并且在电脑上显示相对应名字的到课或者缺课情况。该点名系统设计结构紧凑,易于老师上课花费少量的时间进行上课点名和登记,用户操作方便简单,易于携带跟安装,具有一定的实际应用价值,在多媒体教室功能等方向领域具有较好的发展前景。

In order to optimize the problems of long class roll call time in multimedia classroom and teachers spend a lot of time and energy on roll call and registration, this design uses single chip microcomputer and LD3320 voice recognition module, voice broadcast module and STC USB driver serial port module to form a simple roll call system, recognize the students’ voice of "arrive" or "here", and display the arrival or absence of the corresponding name on the computer. The roll call system is compact in design, easy for teachers to spend a small amount of time in class roll call and registration, easy for users to operate, easy to carry and install, and has a certain practical application value.
