Languages of even small countries can have very regionally specific accents. Accents help give cultures their place-based charm, and a hyper-regionalized sense of place.
In the embedded video above with comedian/actor Fred Armisen (of “Portlandia” fame), he demonstrates how he performs a variety of accents in the United States (and at the tail end of the video you get the difference between Mexican and Cuban Spanish as a bonus). Super strong accents are quite rare, and although they can be emblematic of a place, most people in a place have some elements, but not elements of a regionally distinctive accent.
For Fun, two “bonus” accent clips: first, Fred Armisen again doing accents around the world.
And second, here is one for us Rhode Islanders.
