ELI5: Why do different human languages sound so different but the same animal from around the world sounds so similar?

Human languages are learned, rather than being hardcoded into our DNA.  Most animals don't have a true language; rather they just have a set pattern of sounds that mean certain things.

Some animals, like dolphins and crows, *do* have a (learned) language, and individuals from different parts of the world can't understand each other.  They still sound similar to us, but we probably all sound similar to them.
