Duckling doing a half quack or honk?

This is Scoot, my 3 1/2 week old pekin duckling! Recently I've noticed they've been making this noise a lot more often but I can't place if it's more of a honk or quack! Their sibling makes this noise occasionally as well. Thoughts?

Thanks! It's kind of funny that I'd end up with a girl and a boy duckling, the other duck in that video likes to make little quacking sounds
