Dolphins recorded having a conversation claim researchers from Russia
Researchers from Karadag Nature Reserve Feodosia, Russia claim to have recorded a conversation between a pair of Black Sea bottlenose dolphins called Yasha and Yana. The two dolphins were talking to each other in the pool where they live and the scientists calm that an underwater microphone was able to distinguish the animals' different voices.
According to the researchers, the volume and frequency of pulsed clicks form individual "words" that the dolphins string together in a manner similar to the way humans speak. Scientist have suspected that the mammals had an advanced form of communication that uses distinct clicks and whistles to show emotions like happy, excited, or stressed.
Lead researcher Dr Vyacheslav Ryabov, said, "Essentially, this exchange resembles a conversation between two people."
"Each pulse that is produced by dolphins is different from another by its appearance in the time domain and by the set of spectral components in the frequency domain."
"In this regard, we can assume that each pulse represents a phoneme or a word of the dolphin's spoken language."
"The analysis of numerous pulses registered in our experiments showed that the dolphins took turns in producing [sentences] and did not interrupt each other, which gives reason to believe that each of the dolphins listened to the other's pulses before producing its own."
"This language exhibits all the design features present in the human spoken language, this indicates a high level of intelligence and consciousness in dolphins, and their language can be ostensibly considered a highly developed spoken language, akin to the human language."
According to the scientists, Yasha and Yana can create sentences of up to five words but the researchers don't understand the content of the words. Ryabov is calling for the creation of devices that can overcome the barriers that stand in the way of communicating with dolphins and other intelligent mammals of the world.
