Non-Human Primates and Communication
... Currently, there is no strong evidence for vocal imitation in primates, apart from
humans (but humans are not the only mammals capable of vocal learning).
Nevertheless, non-human primates appear to have some control over their vocal
production. However, vocal flexibility is subtle and often remains ...

plasticity. This term refers to changes that take
place in the neocortex when connections are

... Learning is usually defined as a relatively permanent change in
behaviour or behaviour potential that occurs through experience.
However, it does not refer to behavioural changes that can be explained
by temporary states of maturation.

Vocal learning is the ability to modify acoustic and syntactic sounds, acquire new sounds via imitation, and produce vocalizations. “Vocalizations” in this case refers only to sounds generated by the vocal organ (mammalian larynx or avian syrinx) as opposed to by the lips, teeth, and tongue, which require substantially less motor control. A rare trait, vocal learning is a critical substrate for spoken language and has only been detected in eight animal groups despite the wide array of vocalizing species; these include humans, bats, cetaceans, pinnipeds (seals and sea lions), elephants, and three distantly related bird groups including songbirds, parrots, and hummingbirds. Vocal learning is distinct from auditory learning, or the ability to form memories of sounds heard, a relatively common trait which is present in all vertebrates tested. For example, dogs can be trained to understand the word ""sit"" even though the human word is not in its innate auditory repertoire (auditory learning). However, the dog cannot imitate and produce the word ""sit"" itself as vocal learners can.
