How to Use

Server administrators can open the editor with:

/inner_voice editor

The editor key is unbound by default and can be assigned in Minecraft’s Controls menu.

Create a rule, select its target, choose a track, then configure subtitles, phases, and sounds that should be replaced or reduced.

Only operators with permission level 2 or higher can modify rules. Rules are saved by the server and synchronized with connected players.
