Trivial Tuesday

This week's question is probably going to be answered rather quickly, but I'll ask anyway.  There will be no hints given, so take your best guess.
This man's voice was cobbled together from an AT&T answering system from 1980.  Although antiquated by today's standards, he refuses to update it because it is so recognizable.  Who's voice is it?
Now that I'm reading the question, I would guarantee that the first answer will win.  Oh well, that's the way it goes.  Good luck.
