According to a report of Stuttgarter Zeitung in Germany scientists of the Leibniz-Institute for Wild Animal Research IZW in Berlin use voice recognition to count rhinoceroses. The biologists observe the so-called Sabah-rhinos on the island Borneo, that apparently love to sing while bathing in the marsh. During their observations they want to count the rhinos, this is why the scientists use a modern voice authentication technology to identify the animals.
