Talking about art matters a lot, according to Alastair Sooke, who was a judge in last year's ARTiculation - a little-known, but fast-growing speaking competition, in which teenagers compete to talk eloquently and passionately about art. Alastair has been following the journeys of nine competitors as they have battled their way through nine regional heats, against tough competition, to win a coveted place in the final. And he has been finding out why they took part and what art has inspired them, uncovering the moving, funny and often surprising stories behind their choices. He also catches up with them at the finals in Cambridge, where this year's judge, artist and writer Edmund De Waal, will pick the winner of ARTiculation 2014.
