No voice-overs
Other (objects, etc.) concept
There are no voice overs despite being recent enough that such are commonplace and made by developer/publisher who should've been able to fund such part of development.
Generally small indies do not bother with voice overs so they can be ignored for this fairly safely, though there's really no good way to tell that without deeper investigation so there's no great harm done by tagging them as well.
The format of the game can also be used as guideline for tagging, like text-only games can be expected to not have voice overs even when done by bigger devs and thus tagging them with this would be pointless.
