Oh my... That’s news to me.
It's Austrian German, also called Austrian. The difference is more than accent, apparently. There's also a language in Switzerland known as Swiss. I suspect it's German Swiss, but I'd have to look it up. ;-)
Austria doesn’t call their language “Austrian”, they call it GERMAN... Not “Austrian” German, either... Just GERMAN. The person whose answer he is relying on at WIKI Answers thinks Antarctica recently had a name change, and that “Eleventh” has 4 syllables...
