Talking elephant mimics Korean words
Just weeks after it was revealed that a beluga whale named NOC could
mimic human voices, the journal of Current Biology has released a study
documenting a male Asian elephant named Koshik who can mimic certain
Korean words so accurately that they are understood by native speakers.
In a video, Koshik mimics the word “choah,” which means “good” in
English, but the journal also said he could mimic the words “annoying,”
“sit down,” “no,” and “lie down.” He says the words by putting his trunk
in his mouth and then breathing outward while shaking it. “Human speech
basically has two important aspects, pitch and timbre,” said researcher
Angela Stoeger of the University of Vienna in Austria in a release.
“Intriguingly, the elephant Koshik is capable of matching both pitch and
timbre patterns: He accurately imitates human formants as well as the
voice pitch of his trainers. This is remarkable considering the huge
size, the long vocal tract, and other anatomical differences between an
elephant and a human.”
Researchers also said they didn’t completely understand why Koshik
began imitating the words, but he may have picked them up while he was a
juvenile living as the only elephant in the Everland Zoo in South Korea.
An elephant’s early years are important bonding years, the release said.
“We suggest that Koshik started to adapt his vocalisations to his
human companions to strengthen social affiliation, something that is
also seen in other vocal-learning species - and in very special cases,
also across species,” Stoeger said.While Koshik is the first elephant to
be studied for his human words, there have been earlier reports of
speech mimicry in both African and Asian elephants, including an Asian
elephant living in a zoo in Kazakhstan who was believed to have said
words in both Russian and Kazakh.
African elephants have also been known to mimic the sound of truck
engines, according to Current Biology. While researchers say Korean
native speakers could understand Koshik, they do not believe that
Koshik, himself, understands what he is saying. - grindtv.com
