Interpretation that is executed simultaneously with the presentation of the speaker.
The interpreter works in a soundproof booth at least with one other colleague. The speaker in the conference hall speaks in the microphone and the interpreter listens to the speech in earphones. He interprets the speech nearly simultaneously with the speaker. Every participant to the conference can select a language on the listening box in which he wishes to listen to the speech.
It is recommended on conferences, business meetings with a larger number of participants.
