The Breen language was the language spoken by the Breen. To Human ears, it sounded like garbled electronic sounds. Universal translators needed to be adjusted in order to properly translate the syntax. (DS9: "Strange Bedfellows") Breen could be spoken by a person wearing a Breen refrigeration suit, though it was also possible for that same person to instead speak English while wearing such a uniform. (DS9: "What You Leave Behind", "Indiscretion") Speakers of Breen included Thots Gor and Pran as well as a holographic Breen. (DS9: "'Til Death Do Us Part", "Tacking Into the Wind", et al.; VOY: "Flesh and Blood")
