Trying to imitate a dialect is a slippery slope - especially so in Switzerland. In a country with countless words for something as trivial as the initial slice of a loaf of bread, dialect goes way beyond just pronunciation.
As implied by the Swiss German word for dialect, mouth art ("Mundart"), it is a form of art.
Bligg: Imitating Swiss German
Recently, popular Swiss performer Bligg has attempted to fake various accents in his latest song, "MundArt". On the surface, he seems to be doing quite well - at least for someone who only knows a few stereotypical words in each dialect.

pizAllegra: Linguistic Map of Switzerland
Many years ago, I remember playing around with the Chochichästli Orakel. This website is able to miraculously pinpoint someone's origin by providing a few dialect words. It was truly astonishing how accurate this script was back then, but it has since been enhanced!
pizAllegra is akin to Chochichästli-Orakel 3.0! At the core of the new Swiss dialect locator is a map of Switzerland. All 3200 Swiss cities and towns are represented and can be explored by hovering the mouse over the map. This will in turn reveal a name and postal code.

It located me in my mother's hometown, not far from where I spent most of my childhood and teenage years...
As an added bonus, pizAllegra now includes all four of Switzerland's national languages: German, French, Italian and Romansh.
