With the help of simultaneous interpretation equipment, interpretation is performed in parallel with a speaker’s report, with a delay of few seconds. The speaker does not need to pause so that the interpreter could interpret his/her speech in fragments. Simultaneous interpreters work wearing headphones, sitting in a booth, in which the sound isolation is maintained. As a result, the interpreter’s voice does neither overlap the speaker’s voice, nor hinder the audience from hearing. The audience can hear the interpretation through a special receiver, to which headphones are connected. Simultaneous interpretation is necessary, if more than two working languages are used during an event. In addition, simultaneous interpretation is the indicator of a higher status of an event.


Simultaneous interpretation systems are generally based on the separation of languages ​​into channels. In particular, they enable different participants of the event to hear any given speech in different languages ​​at the same time. Recipients of simultaneous interpretation are equipped with channel selectors; the participants can choose the language acceptable to them and hear all speeches on the same channel.
