This is a British TV Channel Four digital game I learnt through Digital Play. You click on the words and make sentences. The sentence you are making will appear on the bottom left-hand corner. You can edit your sentence, remove words and add new ones.
When you've finished making your sentence, the press the play button just after the sentence you've just made. You'll then see varios British personalities saying the sentence one word at a time. You can see some video samples here.
