【摘要】 随着技术发展和生活水平的提高,人们对家居环境提出了更高要求,智能家居系统已成为目前的该领域的一个重要研究课题。语音是人类最自然的交互方式,利用语音识别与控制技术实现对家用电器的控制是智能家居的重要内容。论文基于微软公司的Microsoft Speech SDK语音开发平台,将语音识别技术集成于嵌入式操作系统Windows XP Embedded中,构建一个智能家居系统,实现对家用电器的语音控制。论文主要工作有:完成基于语音识别控制的智能家居系统方案设计。系统分软件和硬件两部分,上位机实现语音采集和识别、处理,发出相应的动作命令,通过串行通信,构成串行控制网络,控制具备符合接口规范的设备,通过语音实现对家用电器的遥控。对语音识别技术进行研究。经分析比较,采用基于HMM识别算法的Microsoft Speech SDK语音开发平台进行开发。该识别方法具有识别准确率高、便于和操作系统的无缝链接、调用简单方便等优点。研究嵌入式操作系统Windows XP Embedded在本系统中的应用,对系统配置、语音驱动等关键技术进行设计。定制的操作系统可很好的与语音识别软件包相匹配,对硬件配置要求低,有利于降低系统成本。利用单片机构建了执行机构,能和上位机进行可靠通信,并具有红外遥控等复杂控制功能,成本低廉。采用可视化编程完成应用程序设计,界面友好,具备扩展功能,功能增加便利,并便于新控制设备的加入。论文研究的智能家居控制系统能实现对家用电器的有效控制,装设便利、成本低廉、实用性强,并可方便地改造原有家居设备控制系统。论文研究的方法和技术可进一步在其它相关领域得到广泛应用。更多还原

【Abstract】 With development of the technology and improvement of living standards, people ask for a higher demand in domestic environment. In such a case, intelligent home system has become an important research topic in this field. Voice is the most natural interactive mode of human being, so the application of using speech recognition and control technique to control the home appliances has become an important part of the intelligent home research.Basing on the Microsoft Speech SDK Speech development platform, the thesis studied integrates the voice recognition technology in Windows XP Embedded, a kind of embedded operating system, to build a smart home system and then realize the voice control of household appliances.Major jobs are as follows:The completion of the design for the intelligent home control system, which is based on the speech recognition technology. The system composes of software and hardware parts. PC achieves the acquisition, recognition of the voice signals, and handles these signals, then issues Corresponding action commands. Through a serial control network based on serial communication, people can control the equipments with standard Interface, realizing the remote control of household appliances.Research on the voice recognition technology. After some analysis and comparisons, the Microsoft Speech SDK development platform based on HMM recognition algorithm is adopted. This identification method has a high recognition accuracy, can realize the seamless connection to operating system expediently, and has the advantages of easy call.The application of the Embedded System (Windows XP Embedded) in Intelligent Home System . The reserch also designs the key technologies of the system configuration, voice-drive, etc. The customized operating system can match speech recognition software packages well, and with low hardware configuration requirements, it helps to reduce system cost.This system constructs the implementing structure by using Single Chip Micyoco (SCM), and can communicate with PC reliably. Still there are complex control functions such as infrared remote control, but with low cost.The research completes application design by using Visual Programming, with friendly interface, expanded functionality. New functions and control equipments can be increased conveniently.The Intelligent Home Control System researched in this thesis, can achieve the control of household appliances effectively, with convenient installation, low-cost, practical. And the transformation of the original household control system can be conveniently finished .The methods and techniques researched in this thesis can be applied in other related fields extensively.更多还原
