The job duties of a freelance interpreter include working with different clients to interpret from one language into another. A freelance interpreter works on a contract basis. Your responsibilities in this career vary depending on the needs of each client. Some clients ask you to translate spoken language in a live environment, while others need interpreters to interpret from audio files, written text, websites, or other forms of media. Clients typically need you to convert concepts and context into the target language rather than merely translating word for word.
