1. Enter the game, in the area selection interface, there is a button in the upper right corner to automatically turn on "QT Voice", turn it on;

2. When entering the game lobby interface, see In the lower right corner of the taskbar, check whether QT Voice is turned on normally;

3. Since Black Voice is Tencent’s own QT Voice plug-in, if both 1 and 2 are normal and cannot be used, it means that the files in the plug-in have been corrupted. If it's damaged, you can completely uninstall League of Legends, re-download and install the game (Tencent is so bad at this, you can't fix it independently)
