QuickVoice allows QuickChats to be played in your ears straight from the chat (only in LAN matches for now)!
After installing the plugin it should be instantly ready to use.
Some settings can be changed in the BakkesMod GUI (press f2 then go to the plugins tab and click QuickVoice).
In the plugin settings, the plugin can be enabled or disabled, preload sounds for quicker playback, or increase/decrease voice volume.
QuickVoice does not support online matches yet as it could provide a tactical advantage. Hopefully in the future Psyonix approves of it to be used with the exception of tactical chats.
