Cheesy! Like when you listen back, you don't believe it?
I'm going to guess you're a bit insecure about your voice acting... and that maybe you're trying not to scream too loud? Like "I'm going to record a scream, but quietly, so nobody in the other room/outside the house can hear me."
Yes?
It might be that you are not going far enough in character, so instead of being in character in your brain, you're actually trying to scream the way you think the character should scream but your brain is preoccupied with something else (like Do I sound stupid? and Can anyone hear me?). Or you might be trying to still sound pretty while screaming. But really, extreme emotions are always really ugly to see and hear, so our goal is to practice working on relaxing into characterizations.
So my advice is this -- wait until you are 100% home alone, during a time when most neighbors are gone. Get dressed in character as a fighter. Put on war paint on your face, and a helmet if you have one. Take something you can beat up with you into where you record (a stuffed animal maybe?).
Turn on your mic, start recording. Scream just to adjust your gain levels so it's not clipping. Then turn the gain down a little bit further than you need to. Now just let it roll. You'll be deleting most of this because it's an acting exercise, so no worries. You're not trying to impress anyone, you're practicing getting in character to get you out of your own head.
Use your whole room for this: Improvise a scene where you trash talk an enemy (or the stuffed animal). Tell it in the most horrible voices how you're going to destroy its life. Imagine you are the master villain in this story. Be explicit, and laugh cruelly, evilly. Pace, be dramatic. Frighten the hero. What does the hero do? Fight back. Now you do both voices -- Now you are fighting, beat the stuffed thing, hit it against the walls, scream in rage, cry out when you break its legs. "I'll kill you! Get back here!" the villainous you yells, and then "You'll never win! DIE!" the hero shrieks. Thump your chest, bang your helmet, stomp your feet.
Now move to the mic, and keep going with the scene. Try for screams, shrieks, and yells -- happy ones (YES!!!) and crying ones (Noooo... Oh god I was too late! NOOOO!!! WHY!?) with sobs, furious ones, confused ones, go through a range. BE LOUD. IF a neighbor down the street hears you and calls the police, YOU WIN THE GAME.
I have often wondered if today was the day someone would call and report a murder happening, but so far nobody ever has.
Your voice will probably start to feel tight or you'll feel discomfort or pain, because this is tough work. Once you feel discomfort, know that you have a limited amount of time to keep screaming. Try to relax your throat and the back of your tongue while you do it.
Then listen to the last part of what you recorded! See if you believe some of them, pretending to be an objective 3rd party listener. Then take the best couple screams from the series, delete everything else, and go listen to your previous scream that you felt was cheesy. Was there improvement?
As you improve, you'll find that you need props less, and you'll get into character faster. You'll also start noticing how tough this is on your voice, because you're actually using emotion to create your screams, and probably putting all of the emotional tension into physical tension in your throat. So the next step is to practice screaming without that tension. There are some fun videos of metal band singers explaining how they scream, or of vocal coaches teaching how to scream safely. Those are great resources too!
Good luck!
