The plugin has been updated and is available for download here.
However, it requires the newest version to work properly, this is because Overwatch and Civil Protection have separate voices such as numbers as in, 1 2 3 4 5 6 7 8 9 and etc.
See here how to download the current development branch from Clockwork. Don't worry, there should not be any bugs on the development branch since it gets tested. Also if you update to the development branch you also get new features such as multiple voice commands.

I fixed all bugged voices and resorted them all. That took a while though to resort them and see if I have all of the voices added. Also I've changed some long voice commands so they can be played easier.
The isolate voice command is not my fault, its the fault from them: https://steamcommunity.com/sharedfiles/filedetails/?id=175272156 this addon, is basically replacing a few voices... and... that's really bad but, they never let me make an update and they don't allow me to take the addon and reupload a fix. But I guess I will ignore that.
