Place this clip at the end of a talking-head segment, right after the claim you want to question, then let the next shot carry the reaction. For a bigger build, lead into it with a sudden suspense sound, or follow it with a huh reaction for a confused second beat.
關於此聲音
A very short voice clip of a speaker saying “Ok, I believe you” in a flat, matter-of-fact delivery, lasting just over a second. The line lands with dry, doubtful amusement, like acceptance offered while the listener is clearly still unconvinced, which makes the brief statement feel politely sarcastic rather than sincere.
