Scientists discover dolphins ‘can speak almost like humans’
While it has long been acknowledged dolphins are of high intelligence and can communicate within a larger pack, their ability to converse with each other individually has been less understood.
But researchers at the Karadag Nature Reserve, Feodosia, Crimea, believe the pulses, clicks and whistles – of up to five “words” – made by dolphins are listened to fully by another before a response is made.
“Essentially, this exchange resembles a conversation between two people,” wrote lead researcher Dr Vyacheslav Ryabov in the study, published in the journal Mathematics and Physics.
Dr Ryabov said each pulse produced by a dolphin “is different from another” in its time span and the frequencies it emits.
“In this regard, we can assume that each pulse represents a phoneme or a word of the dolphin’s spoken language,” Dr Ryabov wrote.
However: “The dolphin’s speech unfortunately lies beyond the time and frequency characteristics of the human hearing, and is thus unavailable to humans.”
