摘要：语音交互是人类交流和交换信息中最便捷的手段和最重要的媒体，长久以来，人们都希望找寻一种新的途径解决人类与机器的交互方式，希望机器设备能够“听”懂人类的语音信息进行交互，识别其含义并响应、从而做出相应动作，这样的交互方式更能被使用者接受，取代原有的键盘、按钮、开关等传统交互方式，基于非特定人的语音识别技术已然成为人机交互新方式的一个重要发展方向和研究热点。本课题的主要是设计一套基于语音识别的智能家电控制系统。主要分为两个部分：主控系统和子控制设备。通过主控系统获取人发出的语音控制命令，对获得的语音信号进行解析后得到相应指令，对相应指令进行数据打包及加密后通过无线射频芯片发送给子控制设备，子控制设备收到信号后进行相应的解包操作，并对数据的合法性进行检查，如数据无误，则进行相应的操作以实现对家电的控制。32004

The intelligent home control system based on voice
Abstract:     Speech interaction is the most convenient means of human communication and exchange of information and the most important media, for a long time, people want to find a new way to solve the way of interaction between human and machine, machine and equipment can "listen" to understand human speech information interaction, recognition and its meaning, thus make the corresponding response this action, interaction can be more accepted by users, to replace the original keyboard, buttons, switches and other traditional interactive voice recognition technology, speaker has become a new way of human-computer interaction is an important development direction and research focus on. This thesis is mainly to design a set of intelligent home appliances control system based on speech recognition. Mainly pided into two parts: the main control system and control device. Get voice commands issued by the main control system, analysis of the speech signal is obtained after the corresponding instruction, the corresponding instruction data package and encrypted by sending a wireless RF chip to control equipment, control equipment after receiving the signal of the corresponding unpack operation, and check the validity of data. If the data is correct, then the corresponding operation to achieve the control of household appliances.
