Our daily email and Twitter exchanges are littered with variations on spellings that express our emotions. Is your train delayed? You’ll probably splutter an angry "Grrrrrrrrrrr!", while an "Ooooh" is used to convey excitement. That’s what this website looks at. Hover your mouse over the words and a man’s voice will utter them. Warning: it can start to sound a bit, ummmmmm, rude.
