空调的非特定语音辨识与控制

采用STC11L08XE单片机作为主控制器,以LD3320芯片作为外扩语音控制器件,实现语音辨识功能和对空调运行状态的控制,如启动、停止、功能转换、温度调节、定时开关等.该语音控制系统由语音辨识模块、红外线传输模块、LED指示灯模块及按键触发模块组成.根据非特定人声语音辨识方案,设计相应的语音识别程序,并将语音控制系统模块集成到具有红外传输功能的空调遥控器电路中.实验结果表明,根据初始设定的语音命令可实现系统对空调的语音控制,该系统在一定距离范围内具有较高的识别率.

Air Conditioning of Speaker Independent Speech Recognition and Control

Using STC11L08 XE as the main control chip and LD3320 chip as the speech external controller will achieve speech recognition and control the running state of the air conditioning,such as starting,stopping,function conversion,temperature regulation,starting or stopping timely,etc.The voice control system consists of the speech recognition module,the infrared transmitting module,LED indicator module and the matrix key module.According to the speaker independent speech recognition scheme,the author has designed a speech recognition program,and embedded integration module of voice control system into the air conditioning remote control circuit with infrared transmission function.The experimental results show that,speech control on the air conditioning can be realized depending on the initial training voice command.The system has a high recognition rate.
