'Hello!' Says the Human. 'Hello!' Pipes the Orca Right Back. (theguardian.com)
A human greets an orca with a "Hello!" "Hello!" responds the orca. A new research shows, the orcas have been able to imitate human speech, in some cases at the first attempt, saying words such as "hello", "one, two," "Amy", and "bye bye." From a report: The study also shows that the creatures are able to copy unfamiliar sounds produced by other orcas -- including a sound similar to blowing a raspberry. Scientists say the discovery helps to shed light on how different pods of wild killer whales have ended up with distinct dialects, adding weight to the idea that they are the result of imitation between orcas. The creatures are already known for their ability to copy the movements of other orcas, with some reports suggesting they can also mimic the sounds of bottlenose dolphins and sea lions. [...] Wikie is not the first animal to have managed the feat of producing human sounds: dolphins, elephants, parrots, orangutans and even beluga whales have all been captured mimicking our utterances, although they use a range of physical mechanisms to us to do so.
The tits know what really matters in the society of today: they mimic our smartphones.
Koko the gorilla understood a spoken vocabulary of about 2000 words, being able to express a little over half of them in sign. While this certainly sounds impressive, and in truth is impressive for any non-human, a normal 6-year old will typically be able to express 2500 words or more, and has a total receptive vocabulary of usually no fewer than 20,000 words.
In terms of vocabulary, Koko was more roughly the equivalent of a 3 or 4 year old human child, not a 6-year old one.

Also, a 6 year old kid has a grammar (in English, that includes both morphology--a relatively small amount, as languages go--and recursive syntax), and knows how to use it in both speaking and listening. Koko never had a grammar, and in that respect was no more than a two year old. Also, most six year olds in literate countries are well on their way to learning to read and write, and do arithmetic.
