The accent game
A website I found today has a game which shows you a series of short videos of people reading a few lines of a poem in English. Then they ask you to guess the where they’re from based on their accents. If you guess correctly, it also asks you to guess which city they’re from. Some of the people are native English speakers from various countries; the rest are non-native speakers from all over Europe. Visitors to the site can also submit their own videos.
I did better with the native speakers than the non-natives, but got quite a few of the former wrong as well. I’d probably do better if the videos were longer.
Do you know of any similar websites?
