那么免联网的智能家居，是怎么做到识别我们说的话，然后按照我们的指令完成特定动作的？
So how does the Internet free smart home recognize what we say and then complete specific actions according to our instructions?
其实这都要归功于离线语音识别技术。离线语音识别同样运用深度学习等技术，只需在本地进行运算实现人机语音交互，具备离线识别、实时响应等特点。
In fact, this is due to off-line speech recognition technology. Offline speech recognition also uses deep learning and other technologies. It only needs local operation to realize human-computer speech interaction. It has the characteristics of offline recognition, real-time response and so on.
对于离线语音而言，由于其指令相对固定，因此只需对语音指令集进行处理，这对于离线语音识别IC的处理能力要求并不高。
For offline speech, because its instructions are relatively fixed, it only needs to process the speech instruction set, which does not require high processing capacity for offline speech recognition IC.
但这并不意味着离线语音识别是一件非常容易的技术，在实际使用过程中，因识别距离、环境噪音、口音等因素，都会大大影响语音的识别率。
However, this does not mean that off-line speech recognition is a very easy technology. In the actual use process, the recognition rate will be greatly affected by recognition distance, environmental noise, accent and other factors.
