Abstract: Click sounds of dolphins have been made clear in their characteristics and functions but those of whistle sounds are not clear yet. Each whistle has an identical contour and seems to play an important role on their social behavior. According to the contour displayed in sonagrams, whistles were objectively classified by digital analysis. With one exception, 50 whistles were grouped into six classes in the same accuracy as human's eye. This failure was caused by sampling from overlapped signals.
