Language interpretation is the facilitation of oral or sign-language communication, either simultaneously or consecutively, between users of different languages. The process is described by both the words interpreting and interpretation. Translation studies deal with the systematic study of the theory, the description and the application of language interpretation (interpreting) and translation.
Professionals who deliver interpretation are called interpreters. Unlike what many people think, translation and interpretation are different jobs and demand different skills.
There are several types of language interpretation including simultaneous interpreting, consecutive interpreting and whisper interpreting. Interpreters may find themselves in situations needing a combination of all three.
