@zyren We do not want to have manufacturer specific messages in the sound pack, please remove the RadioMaster specific sound, thanks.

[zyren]

@zyren我们不想在声音包中包含制造商特定的消息，请删除 RadioMaster 特定的声音，谢谢。

Thanks for reminding me ，that Hello.wav has been resubmitted, please review

抱歉是我搞错了文件，两个文件名被我搞混了，大意了，还望见谅！

Thanks for updating the hello.wav
For the zh-CN.csv, please change the directory name that matches the directory of the voice files, thanks. en->cn
zh-CN.csv的文件夾跟voice的不符，請改一下。
