+Format of Speech Commands
 -------------------------------
 
-Currently, MultiNet supports up to **200** commands. There are some limitation when designing speech commands:
+Different MultiNets support different format:
 
 -  Chinese
 
-    Use Pinyin for Chinese speech commands, and add a space in between. For example, the Chinese speech command for turning on the air conditioner is "da kai kong tiao"; the Chinese speech command for turning on the green light is "da kai lv se deng".
+    MultiNet5 and MultiNet6 sse Pinyin for Chinese speech commands. Please use :project_file:`tool/multinet_pinyin.py` to get pinyin of Chinese.
 
 -  English
 
-    Use phonetic symbols for English speech commands, and add a space in between. For example, the English speech command for turnning on the light is "TkN nN jc LiT". Users can use the tool provided by us to do the convention. To find this tool, go to :project_file:`tool/multinet_g2p.py` .
-
+    MultiNet5 use phonemes for English speech commands. Simplicity, we use chats to denote different phoneme.Please use :project_file:`tool/multinet_g2p.py` to do the convention.
+    MultiNet6 use grapheme for English speech commands. You do not need any convention.

+不同版本的MultiNet命令词格式不同。命令词需要满足特定的格式，具体如下：
 
 -  中文
 
-    中文命令词需要使用汉语拼音，并且每个字的拼音拼写间要间隔一个空格。比如“打开空调”，应该写成 “da kai kong tiao”，比如“打开绿色灯”，需要写成“da kai lv se deng”。
+    MultiNet5和MultiNet6使用汉语拼音作为基本识别单元，并且每个字的拼音拼写间隔一个空格。比如“打开空调”，应该写成 “da kai kong tiao”，请使用以下工具将汉字转为拼音： :project_file:`tool/multinet_pinyin.py` 。
 
 -  英文
 
-    英文命令词需要使用特定音标表示，每个单词的音标间用空格隔开，比如“turn on the light”，需要写成“TkN nN jc LiT”。具体可使用我们提供的工具进行转换，详细可见： :project_file:`tool/multinet_g2p.py` 。
+    MultiNet5: 使用音标作为基本识别单元。为简单起见，将每个音标映射为单个字母表示，比如“turn on the light”，需要写成“TkN nN jc LiT”。请使用我们提供的工具进行转换，详细可见： :project_file:`tool/multinet_g2p.py` 。
+    MultiNet6: 使用subwords作为识别单元，用户可以直接输入所需短语。比如“turn on the light”，直接写为“turn on the light”即可。
