Interpretation Services: Simultaneous, Consecutive and Remote — How to Choose and Book

Interpreting is bought under time pressure and judged in real time. There is no revision round: whatever the interpreter says is what the audience hears. That makes the booking decisions — mode, number of interpreters, equipment, preparation — more consequential than the hourly rate.

The modes, and what each is for

Simultaneous. The interpreter speaks at the same time as the speaker, from a soundproof booth or with a portable system, and the audience listens through headsets. Used for conferences, large meetings, training and anything with an audience and a schedule. It preserves the event's timing — a two-hour session takes two hours.

Consecutive. The speaker pauses and the interpreter renders what was said, usually from notes. Used for negotiations, interviews, medical and legal appointments, small meetings, site visits and notarial procedures. It is more precise and more controllable, and it roughly doubles the time.

Liaison / escort. Informal two-way interpreting for a visit, a factory tour, a trade fair or a delegation. Flexible, conversational, no equipment.

Whispered (chuchotage). Simultaneous interpreting delivered quietly to one or two listeners without equipment. Suitable for a board meeting where only one person needs the other language — and only for short periods.

Remote (video or phone). Any of the above delivered over a platform. Well suited to short meetings, support calls and medical or administrative appointments; workable for conferences with proper technical set-up.

How many interpreters, honestly

The single most common way to ruin a conference is to book one interpreter for a day of simultaneous work. Concentration degrades sharply after roughly half an hour; professional practice is to work in pairs and rotate. One interpreter can cover a short single session; a full day cannot be done well alone.

For consecutive work, one interpreter is normal, but a long day of back-to-back meetings still needs a break schedule.

Equipment: what you actually need

For simultaneous interpreting on site:

• a booth meeting the usual standards, or a portable "bidule" system for short, small sessions;
• a console with microphones and headphones for the interpreters;
• receivers and headsets for the audience;
• a technician on site — not the venue's AV generalist, but someone who knows interpreting equipment;
• a clean audio feed from the floor microphones, which is the single biggest determinant of interpreting quality.

For remote interpreting:

• a platform with interpreting channels;
• a wired connection for interpreters;
• a microphone for every speaker, not one shared room mic;
• a technical rehearsal, and a moderator who enforces one speaker at a time.

Preparation decides the quality

Interpreters are not simply bilingual; they prepare. Two days before the event, send:

• the agenda and the running order;
• speaker names, titles and the pronunciation of unusual names;
• slide decks, even in draft;
• any script, video or pre-recorded message to be played — videos are the hardest thing to interpret cold;
• acronyms, product names and your internal vocabulary;
• previous minutes or related documents.

If a confidentiality agreement is needed, send it with the material. Interpreters are used to signing them; withholding the material instead is what costs you accuracy.

On the day: brief the speakers to speak at a normal pace, to avoid reading long passages aloud quickly, and to say "as mentioned on slide four" rather than gesturing at it.

Pricing

Interpreting is normally priced per day or per half-day per interpreter, plus:

• travel and accommodation where the assignment is outside the city;
• equipment and technician, if you are not providing them;
• overtime beyond the agreed hours;
• a cancellation fee inside a stated window — interpreters block a day for you and cannot resell it late.

Ask what the quote includes, exactly as you would for written translation; see requesting quotes and, for written work, how much translation costs.

Booking the right provider

Book early for conferences — the pool of qualified conference interpreters in any given language pair is small, and in rare pairs it is tiny. For specialised subjects, say so when booking: a legal hearing, a medical conference and an engineering audit each need a different interpreter.

In the directory, companies offering simultaneous interpretation and consecutive interpretation can be filtered by country and city — useful because on-site interpreting is inherently local. Companies in Cairo, Dubai, Riyadh and Doha cover most regional events, and for a one-off assignment you can also post the request and compare offers.

Before you confirm, agree in writing: the mode, the hours, the number of interpreters, who provides equipment and the technician, the cancellation terms, and the deadline for sending preparation material.

Five mistakes to avoid

1. One interpreter for a day of simultaneous work. Quality collapses in the afternoon.
2. No preparation material. You are paying for expertise and withholding the inputs.
3. One room microphone for ten speakers. No interpreter can fix bad audio.
4. Playing a video with no script. Send the transcript, or expect a summary.
5. Booking a written translator for a spoken assignment. Related professions, different skills — see how to find a professional translator for how to check which one you are hiring.
