About this sound
A Liverpool supporter delivers the line I don't do ifs, buts and maybes in a firm, blunt voice lasting about three seconds, with clear emphasis on each part of the phrase and no music behind it. It feels defiant and final, like a debate being closed. The clip comes from that fan speaking directly to camera.
