Translator or Interpreter?
The fundamental difference between interpretation and translation is the medium: the interpreter works with the oral language, while a translator works with written text.
There are different types of Interpreting.
The interpreter sits with the speaker, listens to a fragment of speech and consecutively renders it in the target language. Consecutive interpreting is suitable for certain kinds of meetings, such as press conferences, roundtables, guided tours, etc.
The interpreter works in a soundproof booth. While the speaker in the meeting room speaks into a microphone, the interpreter receives the sound through a headset and renders the message into a microphone almost simultaneously. Each listener in the audience selects the relevant channel to hear the interpretation in the language of his or her choice. It is widely used in large events, conferences, and presentations.
Whispered interpretation is essentially simultaneous interpreting without a booth. The interpreter sits very close to the listener(s) and provides a simultaneous interpretation in a quiet voice. This mode is mainly used when only very few people need interpretation.
Escort interpreters can help clients while they are traveling. They often act as cultural liaisons, responsible for everything from ordering food to closing important business deals.
