Halloween // Scare actor auditioning while transitioning

So a nearby haunted house is having scare actor auditions this weekend and I'm so excited! This will be the first time I've lived in a place near enough to do this! My problem is that I'm transitioning (ftm) and on testosterone. My main go-to scare before was screaming (which I was pretty good at!) But now my voice has changed and I can barely get out a low half scream before I start coughing. My voice, in general, can't last very long right now either, even for general talking. I don't know what this audition will entail but anything I was originally good at voice-wise is now nearly impossible!

Anyone got any advice for some other things I could pull off at the audition?
