Slurring words!?!?! Well that sucks! But don't you worry. It seems you "some how" just got yourself a bad copy of that video. Try this one from Fox News. It's MUCH clearer.
As to any "confusion" that might have occurred, I've made a fair number of speeches/presentations in my life. Some have gone off without a hitch, and others, well not so much. Travel fatigue, distractions either on-site or in your brain, as well as many other reasons can make one's presentation not quite as smooth as one would like it to be.
As to confusion of historical facts, let me just leave this here...
Airports!!! Really?!?!? Huh!
And who knew that the War of 1812 took place during the American Revolution?!?!?
