Want to take part in a linguistic research project? Check out the VoiceMap project from "Evolving English" from the British Library. You can record yourself reading either six words or the great literary classic Mr. Tickle and to aid in "a unique opportunity to capture contemporary English voices from around the world."
What's cool is you can also listen to recordings of other people from around the world reading the same text. The Irish accents make it sound almost beautiful, while it is creepy and not beautiful when I read it, by the way.
