Brussels, as the de facto capital of the European Union and home to NATO headquarters, hosts hundreds of international conferences every year, bringing together delegates from across the globe. In this demanding multilingual environment, professional simultaneous interpretation is not an optional extra - it is the essential foundation for effective communication, equal participation, and meaningful outcomes for every delegate in the room.
Why international conferences require simultaneous interpretation
Simultaneous interpretation (SI) - whether delivered from a physical booth or via Remote Simultaneous Interpretation (RSI) technology - is the globally recognised standard for large multilingual conferences. The United Nations, the European Union, NATO, and all major intergovernmental bodies rely on it as their primary communication tool. Unlike consecutive interpretation, simultaneous interpreting allows speakers to address the audience at their natural pace while delegates follow the translation in real time through individual headsets, with no interruptions and no loss of conference time.
For a conference bringing together experts, policy-makers, or institutional representatives from multiple countries, every minute spent waiting for a consecutive translation is a minute lost for substantive debate. Simultaneous interpretation eliminates this bottleneck, ensuring that the quality and depth of discussion is identical for an English-speaking, French-speaking, or Dutch-speaking delegate. It is the standard adopted for academic summits, multinational corporate forums, and institutional press conferences held in Brussels and across Belgium.
In practical terms, simultaneous interpretation requires either purpose-built interpretation booths installed in the conference room (the traditional solution for large events) or a portable RSI system using tablets and connected headsets (ideal for venues without built-in booths, or for hybrid events with both in-person and online participants). TranslateBE provides both solutions, with certified interpreters and the right technical equipment for every event configuration.

FAQ
Frequently asked questions
How far in advance should I book an interpreter for an international conference?
For common languages (English, French, Dutch, German, Spanish), we can deploy a simultaneous interpreter within 48 hours. For rarer language combinations (Mandarin, Arabic, Japanese, Russian), we recommend contacting us at least 5 to 7 working days in advance. For large conferences requiring several language pairs simultaneously, a lead time of 2 to 3 weeks allows us to assemble the optimal team and prepare the necessary technical glossaries.
Which languages are available for international conferences in Brussels?
Our network covers more than 70 languages. For conferences in Brussels, the most frequently requested combinations are: English-French-Dutch-German (EU standard), along with Spanish, Italian, Portuguese, Polish, Russian, Arabic, and Mandarin Chinese. We can assemble a multilingual team covering up to 6 languages simultaneously for large plenary conferences, with interpreter rotation every 20–30 minutes in line with AIIC professional standards.
Is RSI equipment included in the interpreter fee?
RSI equipment (headsets, receivers, portable or fixed booth) is quoted separately, as costs vary depending on the size of the event and the venue configuration. If your conference room already has interpretation booths installed - which is often the case in major Brussels hotels and convention centres - only the interpreters need to be booked. For venues without booths, we offer full portable RSI equipment hire including an on-site sound technician.
What is the difference between a physical booth and portable RSI for a conference?
A soundproofed physical booth is the optimal standard: interpreters work in a perfect acoustic environment with no external disturbance, guaranteeing maximum quality over long sessions (full day). Portable RSI (tablets + connected headsets) is more flexible and less costly to set up, making it ideal for events of 2 to 4 hours or venues without existing booths. For conferences with > 200 participants or multi-day events, the physical booth remains the solution recommended by professional associations AIIC and FIT.
