Simultaneous interpretation is the solution of choice for many events, as it is unobtrusive and the original speaker’s words can be interpreted into several different spoken or sign languages in real time. At a conference with interpretation into six languages, for example, everything that is said in any of those languages is translated virtually simultaneously into the other five, enabling speakers of six languages to follow and take part in the meeting. Often incorrectly referred to as “simultaneous translation” or “live translation”, simultaneous interpretation requires professional conference interpreters who have undergone rigorous training.

When interpreting simultaneously, spoken language interpreters work in soundproof booths, preferably with a direct view of the speaker. They listen to the speakers through headsets and interpret their words into the target language in real time, with a delay of just a few seconds. Meeting attendees listen to the interpretation through headsets and can select their language channel of choice. Simultaneous interpretation requires two or three interpreters per target language who take turns to work, alternating every 20 to 30 minutes.
