Place it right after the mistaken name is spoken, then follow it with a confused huh to sell the misunderstanding, and finish with a firm no-no wait wait when the other person tries to argue back.
À propos de ce son
This is a short spoken denial built around the name Miguel, delivered as a quick correction when someone mishears a word. The clipped, matter-of-fact delivery makes it feel funny and awkward, like catching a misunderstanding in real time. It works best as a light pushback, turning a small mix-up into a shared laugh without sounding harsh or confrontational.
