Leopard Gecko voiceless?

[Warrior]

I've read numerous times that, Leopard Geckos unlike some other species of Geckos are voiceless.
However when bathing my Leo to get loose skin from it's toes to come off, he makes sounds like squeaks and chirps.

What is this?

They're definitely not voiceless O_O

They will squeak and chirp whenever they're uncomfortable in my experience and they will even let out a really high pitched squeal when they feel a little too threatened

The new ones that come in at work always hiss and scream when I go to remove their hiding spots and water bowel in fear Im gonna eat them when all Im doing is cleaning

One of mine has never made a peep at all but the other isn't entirely tame I've been hissed at and its squeeked at me before.
