I found this at Rachel’s site. It takes people from hundreds of linguistic groups and has them read the same passage. Each reading then showcases their specific accents. There’s three different readings from Ontario as well as a Quebecois and a Vancouverite. It’s interesting how people who aren’t native English speakers sound as though they take greater care in their speech than those who are. The results can be quite lovely; listen to the Cameroon clip for an example.
