Conference interpreting is the part of the business where planning is everything and the interpreter is the least of the problems. The interpreters we book for a two-day medical congress are excellent. What decides whether the delegates hear them is whether the booth has a sightline to the screen, whether the sound feed from the room is clean, whether the speakers sent their slides, and whether anyone thought about the breakout rooms. Planners who have organized a multilingual meeting once call us at the venue-booking stage the next time.

Simultaneous vs Consecutive Conference Interpreting

Simultaneous Interpreting Equipment: Booths, Receivers and Technicians

We supply and operate the equipment or work with the venue’s installed system. A full setup is a sound-proofed booth per language, built to the ISO standard for mobile booths (ISO 4043) where the venue has no permanent booths to ISO 2603, interpreter consoles, an infrared or radio transmitter, one receiver and headset per delegate, and a technician who sets up the day before, runs the sound and stays until the last session. The booth needs a clear line of sight to the speaker and the screen, a clean audio feed from the room’s microphones, and a place where it will not block a fire exit. For a hybrid meeting, the remote audience hears the interpreted channel through the streaming platform, and remote speakers’ audio has to be routed into the booth.

Why Simultaneous Interpreting Needs Two Interpreters per Booth

Clients new to conference work sometimes ask for one interpreter to save money, and we say no. The standards of AIIC, the international association of conference interpreters, provide that a team is composed of at least two interpreters per language per booth, that an interpreter should not as a rule work alone in a simultaneous booth without a colleague to relieve them, and that a working day should not exceed two sessions of two and a half to three hours each. A booth that relays for other booths from a two-way language needs three. The reason is cognitive: simultaneous interpreting is listening, analyzing and speaking at once, and quality degrades within half an hour. The second interpreter is not idle; they follow the speech, look up terms, note figures and names for their partner, and take over on the turn. A single interpreter for a full day produces a bad afternoon.

Conference Interpreter Daily Rates

Conference interpreters are booked by the day or half day, not by the hour, because a full day of preparation goes into each day of work. As a guide, simultaneous conference interpreters in the US market run about $600 to $1,000 per interpreter per day, and a one-language-pair booth therefore costs roughly double that before equipment. Equipment is quoted separately by the day: booth, consoles, transmitter, receivers per delegate, and the technician. Travel and accommodation are added only when the nearest qualified interpreters are not in the event city. A typical quote for a one-day, one-language conference for 100 delegates has four lines: two interpreters, equipment, technician, and any travel. Rare languages and multi-language relay setups sit above the range. Guide rates for every service are on the pricing page.

Planning Lead Time for Conference Interpreting

Book interpreters when you book the venue. For a common language pair in a major event city such as New York, Chicago or Los Angeles, two to three weeks is workable; for several languages, a rare language, a technical subject or a peak conference month, four to six weeks lets us hold the right team and the equipment. The best conference interpreters are booked months ahead. Once booked, what makes the difference is material: the agenda, speaker names, slides, papers, a glossary, the acronyms your organization uses. A speaker who reads a dense paper at speed without having shared it is the single most common cause of a poor interpreting day. We also ask for a technical contact at the venue and a walk-through the afternoon before.

• Dates, hours, venue and room layout, and whether there are parallel sessions or breakouts
• Languages, and which direction: into English only, both ways, or several languages relayed
• Expected number of delegates needing headsets
• Whether remote speakers or a remote audience are involved, and on which platform
• Agenda, slides, papers, speaker list and glossary, as early as possible
• Subject matter, so the team is matched: medical, legal, financial, engineering, labor relations

Conference interpreters are a different pool from the court and medical interpreters on the rest of this site; a court certification does not make a booth interpreter. For meetings that are not conferences, the on-site interpreting and video remote interpreting pages cover hourly work, and the index at interpreting services sets out every mode. Translation of the conference materials themselves, from slides to proceedings, is handled under business translation.
