After mastering 40 human languages, a Swedish startup has turned to dolphins, hoping to use its language-analysis software to unlock the secrets of communication employed by the aquatic mammals.

Using technology from artificial intelligence language-analysis company Gavagai AB, researchers from Sweden’s KTH Royal Institute of Technology will begin compiling a dolphin-language dictionary. The software will monitor captive bottlenose dolphins at a wildlife park about 90 miles south of Stockholm, the company said in an emailed statement Wednesday.

“We hope to be able to understand dolphins with the help of artificial intelligence technology," Jussi Karlgren, an adjunct professor of language technology at KTH and co-founder of Gavagai, said in the statement. “We know that dolphins have a complex communication system, but we don’t know what they are talking about yet.”
