Animals can’t speak. Humans can. Why? Many animals have no vocal cords.
There are animals that have things seeming like vocal cords, but may not be able to speak like humans because their vocal cords suck. And their breath control is nonexistent. They can merely make sounds.
Parrots can mimic human sounds, but they have no vocal cords. But it doesn’t compare to really speaking.
Sorry animals, but you guys are at a disadvantage when it comes to communication.
