Beluga Whales imitate the human voice
October 23, 2012
A team of researchers demonstrated through acoustic analysis, that the beluga whales can imitate the voices of human beings.
Sam Ridgway, the author of the study published in Current Biology, explained, “The observations suggest that the whale had to modify mechanical voice to imitate the sounds of speech.”
“The investigation began in 1984 when scientists began to notice some unusual sounds in the grounds of the whales. They sounded like two people talking in the distance. These sounds came from a white whale named NOC, who had lived among dolphins and beluga whales, and had been many times in the presence of human beings. “
“The team recorded the sounds of the whale, which revealed similar rhythms and the human voice frequencies several octaves lower than the typical sounds of whales, much closer to the human voice.”
“To perform these sounds, NOC had to vary the pressure in the nasal tract muscle and make other adjustments as well as vestibular inflate the bag in his nostril. Unfortunately, after 30 years at the National Marine Mammal Foundation, NOC died five years ago, but the sound of its voice is still alive”.
