Short definition
In simultaneous interpreting, interpreters render what's said into another language almost instantly – without the speaker having to pause.
Detailed explanation
Simultaneous interpreting is the most demanding form of interpreting and the most important for large conferences. Interpreters hear the speaker through headphones and speak the interpretation into a microphone with just a few seconds' delay, in parallel. Because this requires extreme concentration, two to three interpreters alternate in each booth – typically every 20 to 30 minutes.
The method allows an event to flow smoothly in any number of languages at once, without time lost to pauses. It requires the right technology: a soundproofed booth, interpreter console, language distribution, and receivers. ISO standards 2603/4043 (booths), 20108 (video/audio), and 20109 (equipment) define the framework. It differs from consecutive interpreting through simultaneity, and from whispered interpreting through its full technical equipment.
Relevance in this subject area
Simultaneous interpreting is the core of all conference interpreting technology. Practically every device and standard described in this glossary ultimately exists to make it possible.
Practical example
At an international summit, delegates hear speeches in real time in their own language – made possible by six interpreting booths, each with two interpreters working simultaneously.
