Business and conference interpreting: consecutive, simultaneous and events

In short

Business work uses two main modes. Negotiations and factory visits use consecutive interpreting, which needs no special equipment. Large meetings and seminars use simultaneous interpreting, which needs booths, transmitters and headsets, with two interpreters per language combination as standard practice.

Information to send in advance

Agenda, slides, participant list with titles, product names and any in-house glossary. The earlier this arrives, the more accurate the technical terminology on the day.

Confidentiality

Commercial negotiations and due-diligence work usually require a confidentiality agreement. Define the scope of the information and the term of the obligation in writing before work begins.

Venue and schedule planning

Give the number of rooms, the number of listeners needing headsets and the break schedule, so the interpreter count and equipment can be calculated. Multi-language events need one channel per language.

Interpreting for business meetings and conferences

Business assignments are shaped by the format: a negotiation across a table usually works consecutively, while a conference with an audience usually needs simultaneous interpreting with equipment and a team. The main quality factor is preparation material — agenda, slides, product names and company-specific terminology — supplied before the day rather than on it.

Where bundles usually fail

  • Booking simultaneous interpreting without arranging booths, receivers or a technician
  • Sending slides on the morning of the event, leaving no preparation time
  • Scheduling a full day of simultaneous work without a second interpreter

Questions about this page

What is the difference between consecutive and simultaneous interpreting?

Consecutive interpreting alternates with the speaker and roughly doubles the time needed. Simultaneous interpreting runs in parallel with the speaker and needs equipment and usually two interpreters per language pair.

What material should be sent in advance?

Agenda, participant list, slides, product or contract terminology, and any abbreviations used internally. This is what keeps terminology consistent throughout the session.

Can a confidentiality agreement be signed?

Yes. Confidentiality arrangements are common for commercial assignments and should be agreed before material is shared.

Frequently asked questions

Reviewed August 2026. Requirements change — confirm with the receiving authority before lodging.

What is the difference between a certified translator and a certified interpreter?

NAATI certifies translators for written text and interpreters for spoken language, as separate credentials with separate testing. A practitioner may hold one, the other, or both. Always ask which credential is held for the task you need.

Do Australian courts require a certified interpreter?

Australian courts and tribunals work to their own interpreter policies and generally expect a suitably credentialed interpreter. In Thailand, court interpreting practice is governed by the Office of the Judiciary. Confirm the requirement with the specific court or tribunal, since it varies by jurisdiction and matter type.

Can interpreting be done online?

Remote interpreting by video or telephone is common for consultations, interviews and some hearings, subject to the receiving body's rules. On-site attendance is still required for many formal proceedings.

How do I book an interpreter and what do you need from me?

Tell us the language and dialect, the date, duration and time zone, the setting (medical, legal, business, registry), the mode (on-site or remote) and whether any documents will be read out. Booking availability for rarer languages varies, so give as much notice as you can.

When do I need an interpreter rather than a translator?

A translator works with written documents; an interpreter works with the spoken word. Court hearings, immigration interviews, marriage registration at a Thai district office, notarial signings and medical appointments need an interpreter present, in person or online.

Can an interpreter attend an online hearing or interview?

Yes, where the convening body permits remote attendance. Confirm the platform, the scheduled time in Thailand time and whether the body requires the interpreter's credential details in advance, because some registries need them recorded before the session.

What information should I give when booking an interpreter?

Date and start time with time zone, expected duration, venue or platform, language pair and direction, subject matter, and any documents that will be referred to. Sending the documents in advance materially improves accuracy on technical vocabulary.

Is a court interpreter different from a general one?

Yes. Court and tribunal work requires familiarity with procedure and with the register the bench expects, and some courts keep their own approved list. Tell us the court and the case type when booking so the right practitioner is assigned.

What is the difference between consecutive and simultaneous interpreting?

In consecutive interpreting the speaker pauses and the interpreter renders each segment — normal for interviews, medical consultations and registry appointments. Simultaneous interpreting runs in real time with equipment and suits conferences. Consecutive takes roughly twice the wall-clock time.

How much notice do you need for an interpreter booking?

As much as you can give. Common language pairs can often be arranged at short notice; rarer languages, court settings and on-site attendance outside major cities need longer lead time. Availability varies, so we confirm in writing rather than assume.

Can the interpreter also certify documents used in the session?

Only if that person also holds translator certification for the pair — NAATI tests translators and interpreters separately. Where documents will be read out, send them beforehand so a certified written translation can be prepared in parallel.

Is the interpreter bound by confidentiality?

Practitioners work to the AUSIT Code of Ethics, which covers confidentiality, impartiality and accuracy. An interpreter conveys what is said; they do not advise, summarise, or speak on your behalf.

What is the difference between simultaneous and consecutive interpreting?

Simultaneous interpreting runs in real time, usually with equipment, and suits conferences. Consecutive interpreting alternates with the speaker and suits interviews, medical appointments, registry appointments and most legal settings.

How long can one interpreter work alone?

Professional practice limits continuous simultaneous work and pairs interpreters for longer sessions to protect accuracy. For consecutive assignments, tell us the expected duration so we can staff it properly.

Source: NAATI

What should I send before an interpreting assignment?

Any agenda, names, technical terms, and documents that will be read out. Preparation materials improve accuracy and are handled confidentially.

Can the interpreter give advice during the session?

No. An interpreter conveys what is said, completely and impartially, and does not advise, summarise or advocate. Advice on immigration or law must come from a suitably registered adviser.

Do Thai courts allow interpreters chosen by a party?

Practice is governed by the Office of the Judiciary and by the court hearing the matter. Some courts appoint interpreters directly; others accept one proposed by a party. Confirm with the court in advance.

Source: Office of the Judiciary of Thailand

How does remote interpreting work in practice?

We join a video or telephone session at the agreed time and confirm audio quality first. Stable audio matters more than video, and a headset for each speaker markedly reduces misunderstandings.

What happens if I need to cancel?

Tell us as early as possible so the slot can be released; interpreters reserve time exclusively. Cancellation terms are confirmed in writing with the booking.

Is confidentiality guaranteed?

Interpreters work under professional confidentiality obligations, and NAATI credentialed practitioners are bound by the profession's code of ethics. We can also sign a client confidentiality agreement on request.
