Elephant Mimics Korean Words

Elephant Mimics Korean WordsAn Asian elephant called Koshik has astounded scientists with his Korean language skills. The study is published in the journal Current Biology.

‘Five Korean words’

The study’s lead author Dr Angela Stoeger, from the University of Vienna in Austria, said she first came across Koshik after videos of the elephant, who belongs to Everland Zoo in South Korea, were posted on YouTube. After making contact with the zoo, she went to South Korea to record the animal so she could study its unusual vocal talent. Dr Stoeger and her colleagues found that Koshik’s calls correlated to five Korean words: “annyeong” (hello); “anja” (sit down); “aniya” (no); “nuwo” (lie down) and “choah” (good).

Usually, elephants produce much deeper sounds, sometimes of such a low frequency that they are outside the range of human hearing, and these calls can boom many miles away. While Koshik was capable of producing these more typical elephant noises, he needed the help of his trunk to morph these into something far more human. The researchers said this was behaviour they had not seen before.


‘Anatomic difference’

“He always puts his trunk tip into his mouth and then modulates the oral chamber,” explained Dr Stoeger. ”We don’t have X-rays, so we don’t really know what is going on inside his mouth, but he’s invented a new way way of sound production to match his vocalisations with his human companions.”

She added: “If you consider the huge size of the elephant and the long vocal tract and other anatomic difference – for example he has a trunk instead of lips… and a huge larynx – and he is really matching the voice pitch of his trainers, this is really remarkable.”

But while Koshik sounds convincing, the researchers do not believe that he has any comprehension of the words that he is saying. Instead, they think that the elephant took up talking as a way to bond with his human companions.

Beluga Whale Mimics Human Voice

Beluga Whale Mimics Human VoiceWhile dolphins have been taught to mimic the pattern and durations of sounds in human speech, no animal has spontaneously tried such mimicry. But researchers heard a nine-year-old whale named NOC make sounds octaves below normal, in clipped bursts. The researchers outline in Current Biology just how NOC did it.

‘Reminiscent of human speech’

The whales are known as “canaries of the sea” for their high-pitched chirps, and while a number of anecdotal reports of whales making human-like speech, none had ever been recorded. When a diver at the National Marine Mammal Foundation in California surfaced saying, “Who told me to get out?” the researchers there knew they had another example on their hands.

Once they identified NOC as the culprit, they made the first-ever recordings of the behaviour. They found that vocal bursts averaged about three per second, with pauses reminiscent of human speech. Analysis of the recordings showed that the frequencies within them were spread out into “harmonics” in a way very unlike whales’ normal vocalisations and more like those of humans.


‘Vocal learning’

They then rewarded NOC for the speech-like sounds to teach him to make them on command and fitted him with a pressure transducer within his nasal cavity, where sounds are produced, to monitor just what was going on. They found that he was able to rapidly change the pressure within his nasal cavity to produce the sounds.

“Our observations suggest that the whale had to modify its vocal mechanics in order to make the speech-like sounds,” said Sam Ridgway, president of the National Marine Mammal Foundation and lead author on the paper. ”The sounds we heard were clearly an example of vocal learning by the white whale.”
