Scout- He would try to stay quiet, but he just can’t help being loud! He would whimper a lot imo and no matter if he’s topping or bottoming he moans loudly when he cums. He would also blabber on and on about how good it feels.

Soldier- Definitely vocal, not as much as Scout but loud grunts would come out, if he talked at all it would be loud.

Pyro- The mask keeps them muffled but I think with or without the mask they would be quiet. I can’t see then being very loud in any context (other than during battle)

Heavy- Can’t see him being too loud, though he’s not silent. He would groan and grunt a lot methinks

Demo- I could see him blabbering nonsense and groaning but other than that being quiet? I dunno I can’t really think of much for him… :(

Engie- He would let out low moans and groans but most of the time, he would talk dirty as a way to hide them. He would mutter praises or degrade you but I could see him being a talker.

Sniper- Generally, I can see him being quieter. He would let out quiet moans and if he talked at all, it would be in his quieter voice (I think it’s the one he uses when he’s looking through his rifle, that’s what it says on the wiki anyways.)

Medic- He cannot be quiet for the life of him. If he’s not in a soundproof room, everyone can hear him and knows he’s having sex.

Spy- He would try to keep it down to groans and maybeee a soft moan here and there but I think as he cums he definitely moans a bit loudly. If you tease him, he’ll definitely get louder.
