That princess voice from ghost hunters was so repetitive almost exactly like a voice sampled on a device and it seemed like it was triggered by audio in the room. Just very very computer sample quality to it. So I say it's just too suspicious. Having worked at the History channel too and being directed to make crap up and lie to scare audiences on various other shows.... I dunno. Not very confidence inspiring. So I say it's a deliberate hoax and the crew knew it.
