I can think of many examples of voices that could be described as orotund. Military, police, actors (stage especially), radio announcers, politicians, etc. (to name just a few). “He pitched his orotund voice upon me as if he were giving a command in a gale at sea.” From: A Republic Without a President and Other Stories by Herbert Ward.
