Hungarian scientists are working on computer software analysing dog barks that could allow people to better recognise dogs' basic emotions. Scientists at Budapest's ELTE University have tested software which distinguishes the emotional reaction of 14 dogs of the Hungarian Mudi herding breed to six situations: When the dog is alone, when it sees a ball, it fights, it plays, it encounters a stranger or it goes for a walk. The computer correctly recognized the emotional reaction of the dogs based on their barks and yelps in 43 percent of the cases. People had judged correctly in 40 percent of cases. Scientists said the software could be improved. The research provided further proof that different types of dog barks convey messages humans can understand even if they had no experience with dogs.
