Just checking, because I don't want my players to have to type anything. I just want this to automatically come on for everyone.

The UI is off by default.

I'll add a configuration setting to allow for it to be on by default when I get a few minutes to do it.

Thanks would like to just have this on by default for everyone

I also want this!

I have updated Voice UI to version 1.0.1, this includes the config setting to enable UI by default.

The setting is disabled by default, use this command to enable it.
/voice toggledbydefault true
