Yes, but they do not have vocal cords. Their breathing organs (while breathing) emit a hissing sound.

cutaneous gas exchange
The Nare is a nostril, a frogs nostrils or breathing holes above his mouth.
If you have both, you're most likely an amphibian---this category includes frogs, salamanders, etc.
They sleep on lily pads and breathe out of breathing holes they're ears
Frogs have no proper nose. However, they do have nostrils which are an accessory structure for respiration since frog rely on buccal pumping (breathing with the cheeks) for respiration.
Frogs are born with gills, but soon, when they get older, they get lungs, and start breathing oxygen.
Of corse!! They have to watch out for predators, make sure they eat, drink, and are breathing, they need to look out for cars and other automobiles.
Any breathing process is called respiration, but the way frogs conduct gas exchange through their permeable skins underwater is called osmosis. Wikipedia has a brief and easily readable post on the way a frog does this. Need a link? Hey, this is WikiAnswers. We got yer back. You'll find the link below.
Poison arrow frogs secrete a venom through their skin that can cause paralysis, nausea, breathing difficulties, and death in people. It is believed to be a lipophilic alkaloid toxin that does the most damage. Poison arrow frogs sequester their poisons from their food (such as ants). If not raised on poisonous insects, they will not secrete poisons from their skins.
