This is Chinese Female Voice pack for DBM Shadowlands. (This is not a standalone addon but a plugin to DBM. Make sure you download DBM first). After downloading, please config voice warning option in /dbm as Weiwei（微微·国语版）。
For WOW classic: please edit toc file, change game version into 11302 本包兼容WOW classic, 自己改toc版本到11302
DBM微微语音包
女性普通话 国语
配上Alpha版DBM即可使用. 记得在/dbm主菜单里将语音选项改为Weiwei(微微·国语版)。
BTW, you may need the latest alpha DBM to make the best use of it at this early stage. We are still adding more voices and so is DBM.
