智能空调语音控制系统开发

摘要

With the continuous development of society and the gradual improvement of people's living standards,people have a higher demand for their own living environment level,the requirement on functional diversity and convenience of household equipment is also constantly improved.Based on this background,this design uses the existing speech recognition chip to identify the speech input,so as to realize human-computer communication.And then the speech chip non-specific speech recognition technology is adopted to accurately identify the speech command issued by the speech chip LD3320,the speech command will be converted into digital signal transmitted to the main control system.The controller of the main control system adopts the STC89C52RC,which receives the signal from the speech module and processes it.Furthermore,it sends the control information to the infrared transmitting module,and transmits the control information to the intelligent air-conditioner by the infrared transmitter.The experimental result shows that the speech control system can achieve the desired purpose and has a good application prospect.%随着社会经济不断的发展和人们生活水平的提高,人们对家居功能的多样化和使用的便捷性要求也在不断地提高.基于这一背景本设计利用语音识别芯片对语音进行录入、识别,进而实现人机交互.系统采用非特定人语音识别技术,通过语音芯片LD3320准确的识别出入发出的语音控制指令,并将其转换成数字信号传送给主控制系统.主控系统的控制器采用STC89C52RC单片机,单片机接收来自语音模块的信号后,对其进行处理,生成控制信息发送给红外线发射模块,再由红外线发射器将控制信息发射给智能空调.试验表明,本语音控制系统能够达到预期目的,具有较好的应用前景.
