I believe that leachies are the most vocal of all geckos. They can make all sorts of different vocalizations in varying volumes and can be quite loud. I have a pair of leachies and the male is pretty quiet but the female makes all kinds of noises from barking, chirping, and clicking to other interesting calls. If she is out and about and I move a hand too close to her cage while feeding or cleaning the cages around hers she barks at me and sometimes scares me to death when she lets out a loud one. One time she was making a weird whiny kind of noise and my husband thought one of the cats was stuck somewhere. Gotta love it, but I will say that leachies may not be best kept in any room where you sleep.
