【摘要】 随着人们生活水平的逐渐提高和电子、通信技术的不断进步,智能家居也日益被人们所接受。然而在人机接口方面还只是局限于手动操作,如按键和触摸屏等,没有实现真正的人机对话。解决这一问题的一种办法是将语音识别技术引入到智能家居中,针对这一状况本文主要从以下几个方面展开了研究：第一,充分利用凌阳SPCE061A非常适合处理数字语音信号的特点,设计了一套基于SPCE061A的智能家居系统。该系统能进行语音指令的识别和执行,大大改善了人机交互界面。第二,利用电话网,采用双音频解码芯片MT8870实现了对家用电器的远程控制。无需另外布线,使系统结构更加简单。第三,在凌阳IDE2.0.1环境下,利用C语言、汇编语言进行软件编程,底层驱动程序采用汇编语言,对外给出C语言的调用接口。语音方面的程序以库的形式给出,由于SPCE061A处理芯片内已封装了高效的语音播放及识别接口函数,建立语音命令模型,包括提示性的语音播放命令和程序内部操作处理命令等。论文提出了利用凌阳SPCE061A单片机来实现把语音识别应用于电话控制中,实现了语音控制家用电器。本系统的每一个接口电路如振铃检测、模拟摘挂机、语音提示、双音频解码电路都已经过交换机在线实验,具有很强的实用性。该系统具有人机交互性好、结构简单、可靠性好、性价比高等优点,更易于推广和应用。更多还原

【Abstract】 With the rising of the living standard of people and the development of the technology in electronic and communication, the smart home system is admitted by people gradually. However, the human-computer interaction is still rest on manual acting, such as key-press, touching screen and so on. In order to accommodate this command of people, we need to add the technology of speech recognition to the smart home system. This paper mainly deploys the following researches:First, making good use of the SPEC061A which has the peculiarity of dealing with speech signal, we design a smart home system to recognize and carry through the speech dictation of people. This improves the human-machine conversation consumedly.Second, having designed a system which can realize remote control based on telephone line. We can control the home equipment by DTMF code. No extra wire is needed in this system, so the structure of the system is very simple.Third, the soft program is based on the unspIDE2.0.0, and commixes the compilation and C language, the bottom driver program is made by compilation language and gives an interface to the C function. The program of speech is given by function library. We create a model of speech command before the program starts as the SPCE061A has packaged speech play and recognition function. The model includes attention programs of speech command and command of operational program.We use SPCE061A to realize the speech recognition application in the smart home for the first time. Every interface circuit such as the circuit of ring detection, analog packing and hitching, speech prompting, DTMF decoding and so on of the system has realized the consummate function using the simpler circuit and the cheaper chip. Compared with the traditional system, this system has merit such as good human machine interface, simple structure, good reliability and high ratio of performance to price and so on, all of these make it very easily to be extended and used.更多还原
