This assumes that, given the right pronunciation, people will be able to pronounce your name correctly. That's just not reality. I've corrected many a person many a time only to have them repeat the same pronunciation back to me as they did before I corrected them two seconds ago. Finally, I just gave up.

Now I have two first names.

EDIT: Also happens a lot on voicemails, seconds after they've clearly heard my first name pronounced (the last name I don't mind much as it is unusual).
