Interpreting is the rendering of information from one language to another. This is performed in two main ways; simultaneous interpreting and consecutive interpreting. Chuchotage is an additional mode of interpreting.

Simultaneous Interpreting

During simultaneous interpreting, a pair of interpreters takes turns at listening to the speaker and simultaneously interpreting the original message into a desired target language with as small a delay as possible. Simultaneous interpreting usually requires a soundproof booth, microphones for the interpreters and original speakers and headsets for all those present. This type of interpreting is most frequently used at conferences and meetings of international organisations.

Consecutive Interpreting

During consecutive interpreting, the interpreter takes specialized interpreting notes of smaller segments of the original speech and renders these into the target language in chunks of approximately seven to ten minutes after the original speaker has finished.
