What Is Simultaneous Interpreting?

In simultaneous interpreting, the interpreter translates in real time while the speaker is still talking. There is no pause — the audience hears the translation through headsets only a few seconds behind the original speech. This keeps your event flowing naturally, maintains momentum and allows all participants to follow along in their own language.

This differs fundamentally from consecutive interpreting, where the speaker pauses after every few sentences and the interpreter then translates. Consecutive interpreting roughly doubles the speaking time; simultaneous interpreting does not.

Why two interpreters? Simultaneous interpreting is one of the most cognitively demanding tasks a human can perform — listening, translating and speaking at the same time without interruption. To maintain accuracy and prevent fatigue, simultaneous interpreters always work in pairs, alternating every 20 to 30 minutes.

When Do You Need Simultaneous Interpreting?

International Conferences

Multilingual events with large audiences where pausing for translation would break the flow. Keynotes, panel discussions and plenary sessions run smoothly with simultaneous interpreting.

EU & Government Meetings

Official multilingual proceedings — council meetings, parliamentary sessions, policy roundtables — where every delegate must follow in their own language in real time.

Corporate Board Meetings

International boards with members in multiple languages. Simultaneous interpreting keeps discussions efficient without doubling the meeting time.

Shareholder & AGM Events

Annual general meetings with international shareholders who need to follow presentations, vote and ask questions — all in their own language.

Medical & Scientific Symposia

Research presentations, clinical seminars and international congresses where precision and domain-specific terminology are critical.

Webinars & Hybrid Events

Remote and hybrid events with international audiences. Simultaneous interpreting works just as effectively over platforms like Zoom, Teams and dedicated RSI tools.


Simultaneous vs. Consecutive: Which Do You Need?

Choose Simultaneous When...

Your event has large audiences, multiple languages, time pressure or a formal programme. Speeches, presentations and panel discussions flow best with simultaneous interpreting. The audience listens via headsets and hears the translation in real time.

Choose Consecutive When...

Your setting is smaller and more interactive — business meetings, negotiations, medical consultations or notarial appointments. The interpreter listens, takes notes and then translates. No equipment needed, but the session takes roughly twice as long.

Why Preparation Is Critical

Simultaneous interpreting demands peak concentration and rapid processing. The better prepared the interpreters are, the higher the quality of interpretation your audience receives. Here is what helps:

  • Share the programme and schedule — so interpreters know the flow, the topics and the transitions
  • Provide speaker presentations in advance — slides, papers and talking points allow interpreters to prepare terminology
  • Send glossaries or key terms — especially for technical, legal or medical events with specialised vocabulary
  • Clarify names and acronyms — organisational names, project codes and abbreviations that the interpreters will hear
  • Confirm the language combinations — which source and target languages are needed, and whether relay interpreting is required
  • Discuss the technical setup — on-site booth, hub interpreter or remote simultaneous interpreting (RSI) platform

How to Book Conference Interpreters

  1. Describe your event — date, location (or online platform), number of languages, audience size and subject matter.
  2. Receive a tailored recommendation — we advise on the number of interpreters, format (booth, RSI, whispered) and equipment needs.
  3. Review interpreter profiles — see qualifications, conference experience, language pairs and client reviews on the platform.
  4. Share preparation materials — upload presentations, glossaries and the event programme so interpreters can prepare.
  5. Your event runs smoothly — trained interpreter pairs deliver real-time translation while your speakers present without interruption.

On-Site, Remote or Hybrid

On-Site (Booth Interpreting)

Interpreters work from a soundproof booth at the venue. The audience wears headsets tuned to their language channel. This is the traditional conference setup — ideal for large in-person events with multiple language tracks.

Remote (RSI)

Remote Simultaneous Interpreting uses cloud-based platforms. Interpreters work from their own professional setup, listeners select their language channel online. No booth, no travel — lower cost and fast to arrange, especially for webinars and virtual conferences.

Hybrid events — where some participants are on-site and others join remotely — combine both setups. Tolk2Go can help you find interpreters experienced in any format.

Frequently Asked Questions

How many interpreters do I need for simultaneous interpreting?

A minimum of two interpreters per language combination. Simultaneous interpreting is extremely demanding — interpreters alternate every 20 to 30 minutes to maintain accuracy. For events longer than a full day or with highly technical content, three interpreters may be recommended.

What is the difference between simultaneous and consecutive interpreting?

In simultaneous interpreting, the interpreter translates in real time while the speaker talks — the audience hears the translation through headsets with only a few seconds' delay. In consecutive interpreting, the speaker pauses and the interpreter then translates what was said. Simultaneous is used for conferences and large events; consecutive for smaller meetings and consultations.

Do I need to arrange interpreting equipment (booths, headsets)?

For on-site simultaneous interpreting, you will need a soundproof booth, headsets for the audience and a sound system. Tolk2Go can advise on equipment providers. For remote (RSI) events, all you need is a compatible online platform — no physical equipment required.

Can simultaneous interpreting be done remotely?

Yes. Remote Simultaneous Interpreting (RSI) is widely used for webinars, virtual conferences and hybrid events. Interpreters work from their professional setup using cloud-based platforms. Listeners select their language channel online. RSI reduces costs and travel while maintaining the same quality.

What is whispered interpreting (chuchotage)?

Whispered interpreting is a form of simultaneous interpreting where the interpreter sits next to the listener and whispers the translation in real time — no booth or headsets needed. This works well when only one or two people need interpretation, such as a visiting executive during a board meeting.

How far in advance should I book conference interpreters?

For major conferences and multilingual events, book as early as possible — ideally four to six weeks ahead. This gives interpreters time to prepare and ensures availability for your language combinations. For smaller events or common languages, shorter lead times are often possible through Tolk2Go's large network.

What does simultaneous interpreting cost?

Costs depend on the language combination, event duration, number of interpreters needed and whether the event is on-site or remote. All pricing on Tolk2Go is transparent — you see the interpreter's rate, preparation fees and any travel costs before booking. Contact us for a tailored quote.
