This is a very short spoken clip of Dumbledore saying the single word Ravenclaw in his calm, deep voice, lasting just over a second. It feels warm, ceremonious and quietly magical, like a formal house announcement made for a proud member of that house. The line comes from the Harry Potter films, where Dumbledore names the Hogwarts house.
