We’ve known for decades that dolphins communicate at advanced levels, but now, for the first time, dolphins have been recorded forming individual words strung into sentences. Researchers at the Karadag Nature Reserve observed that each dolphin would form words by altering the volume and recency of pulsed clicks, and that the other dolphin would listen without interrupting before replying.
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.”
