About this sound
This is a short 1.7-second voice clip from the television game show Family Feud, built around the pointed phrase 'you said' as an answer is read back to a contestant. The delivery is blunt and slightly incredulous, giving it an awkward, gotcha feeling that lands best when someone has just confidently given the wrong answer.
