This isn't completely true: even within America, there's different accents. So people with a "standard American accent" (generally midwestern) listen to Southerners talk and say they have an accent. There's also northeastern accents (such as the famous Boston accent). Of course, these days, a lot of the accents are disappearing because of mass communications, so the "American accent" is homogenizing, but those other accents aren't completely gone yet.
