About this sound
This voice clip lasts about three seconds and has a speaker calling out in Portuguese the line 'Olha, quem tá na televisão', meaning look who is on television. It gives a listener a burst of excited recognition, like spotting someone familiar on screen and wanting everyone nearby to notice at the exact same moment before the scene moves on.
