So, uh. This is kinda a guide / question thing.
This is how I attempt to do the predator noise.
Bare teeth, sorta smile. Get teeth as close as possible without touching top teeth to bottom.
Touch tongue to the top of your mouth, right behind your top teeth.
Blow out of your mouth normally. Now, use your uvula while blowing, and you should feel a vibrating near the middle of your throat. Make sure you don’t have any spit in your mouth while doing this. Keep practicing.
4.Make sure to not attempt to force the noise, be calm, and do it lightly. Think of it as an instrument, don’t blow hard, it makes the noise break up, do it very light, like a whistle of an alien skull collector, not the aggressive blowing of an alien skull collector.
Practice this for a few hours, days, weeks, and pucker, or widen out your lips for higher or lower clicks, and direct your lips up for low clicks,
down for high pitched clicks.
It isn’t perfect, but it should work.
So, to anyone responding, tell me how you make the noise, and how this method worked for you!
