Place it just before a decision or reveal in your edit, then follow it with Ceeday Huh for a second reaction, or let No No Wait Wait cut in when the choice suddenly changes. Keep it early so the moment sets up the payoff that follows.

This clip is a single drawn-out human hum, lasting about one and a half seconds, with the voice rising and falling gently on one long mmm sound. It feels uncertain and thoughtful, like someone weighing an idea out loud without committing to an answer. The soft, wavering tone makes it easy to read as hesitation, curiosity or quiet agreement.
