Carolina wrens sing year round and at any point during the daytime, with the exception of performing during the most harsh weather conditions. Males alone sing, and have a repertoire of at least twenty different phrase patterns and on average, thirty two. One of these patterns is repeated for several minutes, and although the male’s song can be repeated up to twelve times, the general amount of songs range from three to five times in repetition. While singing, the tail of the birds is pointed downward. Some general vocalizations have been transcribed as teakettle-teakettle-teakettle and cheery-cheery-cheery. Various descriptions of the teakettle song include whee-udel, whee-udel, whee-udel, che-wortel, che-wortel and túrtee-túrtee-túrtee and familiar names and phrases such as sweet heart, sweet heart, come to me, come to me, sweet William, and Richelieu, Richelieu.
