Abstract: A phonetic alphabet for communicating with dolphins, porpoises and whales includes three basic geometric shapes, various combinations of which are used to represent speech sounds. The alphabet consists of eighteen symbols which may be understood by animals trained to identify these symbols with words by using their innate echolocation sensory capabilities, and may also be understood visually by human trainers.
