I have a small Pyxie frog (2.5-ish inches at the moment, I think he's probably a dwarf), and I hear squeaky/chirping noises from his tank every now and then. I can't tell if it's a vocalization or just him trying to burrow into the glass bottom, especially since I seem to hear it more when I've just cleaned his tank so the bottom is wetter...?? It really sounds like a vocalization and he's been doing it a LOT in the past 12 hours (just cleaned his tank), but I can't find anything that says whether or not they make noise and what it sounds like.
