摘要
基于单片机模块、LD3320语音识别模块和双自由度云台模块,设计了一种具备非特定人语音识别能力的智能语音控制系统——智能地球仪。该地球仪通过智能识别用户给出任一国家名称的命令驱动云台转动使地球仪上的目标国家正对用户,同时点亮代表该国家首都的LED灯,并播放该国家的概况信息。此地球仪可应用于地理教学中,是一种性能可靠、功能强大、趣味性强的教学模具。
Intelligent voice control systems—intelligent globe with the ability of speaker-independent speech recognition is designed based on 89S52 single-chip computer module,LD3320 speech recognition module and double-DOF pan-tilt module.The system can recognize the commands of any speaker intelligently,turn the pan-tilt to make the spoken country faced to the user,light the LED backlight of the capital,and narrate the general information of the country.The intelligent globe has been successfully applied in the teaching of geography as an interesting teaching mould with reliable performance and strong function.
