The interpreter works in a soundproof booth with at least one colleague. The speaker in the meeting room talks into a microphone; the interpreter hears the speech through a headset and renders the message into a microphone almost instantly. Each participant in the meeting room selects the relevant channel to hear the interpretation in the language of their choice.
There are many different possible configurations of languages and equipment.
This service can be performed remotely, under certain conditions.
The different types of interpretation
The interpreter sits with the participants, listens to what is said, generally whilst taking notes, and then renders it in a different language, once the speaker has finished.
