Officials at Everland amusement park in South Korea are set to showcase a pachyderm who can mimic human sounds perfectly. The 16-year-old male Asian elephant, named Kosik, is able to imitate sound of as many as eight Korean words including, "sit," "no," "yes," and "lie down."

Although researches have shown that elephants can mimic sounds, like that of a truck, but Kosik's ability is believed to be unique since it produces human like sounds.

Authorities said that they were, however, unsure that whether Kosik know the meaning of the sounds he makes.

Kim Jong-gap, who has been Kosik's keeper for 10 years, said he first heard the elephant speak two years ago.

"It was hard to believe myself at first," Kim said in a statement. "As I watched Kosik say something after that, I realized he was mimicking my words."

Spectrograms have shown that Kosik's voice frequency while making human sounds nearly match to that of his keeper, Everland said.

"We are speculating that Kosik learned to speak as he spent a long time with his keeper," said Kwon Su-wan, head of the park's zoo. "We plan to conduct further studies with keepers, veterinarians and scientists on whether Kosik understands the meaning of these words as he speaks them."

Kosik will showcase his ability to the public starting Saturday at the park in Yongin, some 30 miles south of Seoul.
