Human mind always senses if there’s something odd. I couldn’t help but observe that Satya Nadella’s voice seems a bit odd for the background… he is in a room (at least that’s what the backdrop makes you feel). But his voice seems like all the echo/acoustics, that makes you feel like someone is speaking inside a room, is completely absent. This makes it sound as if he is speaking in a studio, on a mic. I wish they used some AI driven audio correction to make him sound more natural, in a room.
