说明：  产品特性： 高准确度和实用的语音识别效果。 非特定人语音识别技术：不需要用户进行录音训练。 可动态编辑的识别关键词列表：只需要把识别的关键词以字符串的形式传送进芯片，即可以在下次识别中立即生效。比如，用户在51等MCU的编程中，简单地通过设置芯片的寄存器，把诸如"你好"这样的识别关键词的内容动态地传入芯片中，芯片就可以识别这样设定的关键词语了。 支持用户自由编辑50条关键词：在同一时刻，最多在50条关键词语中进行识别，终端用户可以根据场景需要，随时编辑和更新这50条关键词语的内容。
(Product characteristics: High accuracy and practical speech recognition results. Speaker independent speech recognition technology: there is no need for users to record training. A list of recognizable key words that can be dynamically edited: it is only necessary to send the identified keywords in the form of a string into the chip, that is, it can take effect immediately in the next recognition. For example, in the programming of 51 MCU, users simply set the chip's registers and dynamically transfer the content of the identified key words such as "hello" into the chip, and the chip can identify the key words that are set. Support the user to edit 50 key words: at the same time, at the same time, at most of the 50 key words, the end user can edit and update the content of the 50 key words at any time according to the needs of the scene.)
