整个智能家居语音控制系统主要由移动终端语音控制软件和嵌入式便携式语音控制器组成。
[En]
The whole intelligent home voice control system is mainly composed of mobile terminal voice control software and embedded portable voice controller.
安装有移动终端语音控制软件的终端在接收到本地语音信息后，通过网络(3G、GPRS、WiFi)将本地语音信息发送到讯飞语音云进行识别，再将云端反馈的数据解析并与本地设置指令匹配，获得正确的控制指令。
通过服务器和网关将这些指令转发给相应的设备执行动作指令，可以随时随地控制家中设备的语音。
[En]
Through the server and gateway to forward these instructions to the corresponding devices for the execution of action instructions, we can control the voice of the devices in the home anytime and anywhere.
嵌入式便携式语音控制器通过家庭网关集成到智能家居无线传感器网络中，终端在本地识别语音信息，并将相应的控制指令转发给网关，网关和服务器转发给相应的设备执行动作指令。
[En]
The embedded portable voice controller is integrated into the smart home wireless sensor network through the home gateway, and the terminal recognizes the voice information locally and forwards the corresponding control instructions to the gateway, which is forwarded to the corresponding devices through the gateway and server to execute the action instructions.

Technology used in Voice Control Intelligent Home system
人们通过语音与机器交流，让机器听懂你在说什么，这一直是人们的梦想。语音识别技术是允许机器通过识别和理解的过程将语音信号转换成相应的文本或命令的技术。
[En]
It has long been a dream for people to communicate with the machine by voice and let the machine understand what you are saying. Speech recognition technology is the technology that allows the machine to transform the speech signal into the corresponding text or command through the process of recognition and understanding.
语音识别是一门交叉学科。语音识别技术和语音合成技术的结合，使人们摆脱了键盘，通过语音命令进行操作。语音技术的应用已成为竞争激烈的高新技术产业。
[En]
Speech recognition is a cross-discipline. The combination of speech recognition technology and speech synthesis technology enables people to get rid of the keyboard and operate through voice commands. The application of speech technology has become a competitive new high-tech industry.
远场语音识别是将麦克风阵列拾取的语音数据作为输入数据，通过语音识别算法将语音信号转换为文本的技术。
[En]
Far-field speech recognition is a technology that takes the speech data picked up by the microphone array as the input data and transforms the speech signal into text through the speech recognition algorithm.
虽然原理上与近场语音识别技术相同，但由于声源与麦克风之间的空间距离增大，在声波传播过程中会出现信号强度衰减和各种噪声干扰。因此，需要特殊的语音数据提取和预处理技术。
[En]
Although it is the same as the near-field speech recognition technology in principle, due to the increase of the space distance between the sound source and the microphone, there will be signal intensity attenuation and all kinds of noise interference in the process of sound wave propagation. therefore, special speech data picking and preprocessing techniques are needed.
不同的拾音设备和预处理技术往往会改变用于语音识别的声学信号的特性，因此对于不同的远场语音拾取技术，有必要对语音识别引擎进行定制和优化。
[En]
Different pickup devices and preprocessing techniques often change the characteristics of acoustic signals used in speech recognition, so for different far-field speech pickup technologies, it is necessary to customize and optimize the speech recognition engine.
