Yeah it's AI... I actually couldn't handle watching it or even listening. It didn't have McGregor's 'essence' and 'human-ness'.
You can tell from the eyes - even though AI is clever and getting 'better' doing all it can to mimic human behaviour even down to making it look like MacGregor really is reading from a screen, and the skin on his neck was moving (that sounds creepy!) but the blinks and expressions are 'wrong': there are no natural pauses, no real change in tone, no 'breath'... no space for the listener to receive more deeply, to emphasise a point or even express genuine emotion (ie: concern) on some level.
