Does Obama read his speeches or are they memorized?

Question

If you look at videos of his speeches on youtube (e.g the one in Berlin), he delivers them so well, hardly any pauses, on time, on message. Surely he must be reading them from a screen cast?

Answer 1

Teleprompter

Answer 2

just look at everybody from the convention, not one could speak for themselves they all had their eyes on the prompter, yelp what i want to elect people who are puppets

Answer 3

He reads them but puts a lot of his Communist manifesto language into them

Answer 4

Memorize...hahaha...that's pretty funny.

Answer 5

He reads them from several teleprompters placed strategically about the room.  

Answer 6

It's his programming. He has a 20 GB ram just for speeches and public appearances. the programmers are trying to make it look spontaneous before the debates.

Answer 7

Both (no sincerity).
