I Learned How to Pronounce Words in Jamaica, Mon!

I found this kids website from the BBC the other day. It has educational games for English and Maths (which is British for math) for early elementary students. I tried several of the games and found them quite fun. The most fun part for me was called Space Spins. When you pull a virtual lever, a sentence appears on the screen and is read aloud to you, in a very strong West Indies accent! Wha? The idea is to learn to read, I believe, but the story reader is the only voice on the program that speaks anything other than Received Pronunciation. So why is the vocabulary program speaking like Miss Cleo? Who knows, but it's hilarious!
