Which of these 5 persons is the voice behind Big Brother?

1. Ebuka

Everybody knows Ebuka Obi Uchendu is the host of Big Brother Nigeria, but is he more than just the host? Is he also the faceless voice playing God from the speakers everyday?

If you listen closely, sometimes Big Brother sounds just like Ebuka, but then, the host has been spotted in Lagos several times since the reality show started. Meaning he is either one of those playing Big Brother, or he is not, at all.
