To further clarify: a voice bark is edited using the voicebark editor. Every entry in a voicebark is an automated dialog (possibly multiple times the same automated dialog) followed by the conditions under which that dialog should be selected (depending on the number of available player speakers, and their tags).
The automated dialogs referenced by the voice barks in turn have to be created in the
dialog editor. The dialog editor itself also supports "voice bark" as dialog entry, but the code does not treat this different to "Automated NPC Dialog"s in any way.
