"Most" is indeed key. For example, as far as "complex vocal patterns" go, there are birds which can learn to duplicate human speech and therefore have the vocal capacity of humans. Or, as far as bipedalism goes, you have the kangaroo -- and actually, if I count the animals that I've seen take a few steps on their hind legs, I'd have to also include dogs, a rabbit, a gerbil, and an elephant that was trying to get his mating on. Even our nakedness is shared by other species -- one of them is called the naked mole rat.
Also birds for bipedalism. At the extreme we have ostriches and emus.
BTW: cockatoos also have strikingly manipulative feet, which they use in combination with their beak (though they can't use both feet simultaneously). And a surprisingly high brain/body ratio. Although they lack a prefrontal cortex, birds have separately developed a different structure, called the hyperpallium. There's no necessary barrier for birds evolving sapience independently from our line (any more than for aliens) - and there's no reason that the architecture of our brains must be better/more efficient.
