How fake can one’s voice be?

Were they not given any instructions/guidance to how to actually host/anchor? Rida still is okay (overacting though) but what is with Rebel’s voice? So fake omg. I am literally cringing.

Why do shows aim to provide platform to those who aren’t fit for the job? Even if this is your first time, put some efforts into it na. Smh. 🤦🏽‍♀️
