Simultaneous Interpreter vs Consecutive Interpretation

A simultaneous interpreter speaks while the floor speaker continues, so the audience hears the other language almost at the same time. Consecutive interpretation waits. The speaker pauses, then the interpreter delivers that stretch before the speaker goes on. The choice changes the length of the programme, the equipment, and the kind of room you can use. Fees for either are on request and depend on the languages, the hours and the size of the team.

Organisers often ask for “translation” and mean one of these two. They are both interpreting. Written translation is a third job and is not what this note covers. If you are unsure which spoken format you need, describe the sessions in the request rather than naming a package.

How each format works

In simultaneous work the interpreter is usually in a booth, or at a table that is actually quiet, hearing the floor through a direct feed and speaking into a microphone that feeds headsets. The speaker does not wait. The interpreter has to keep up, including when the speaker reads a text, changes language, or abandons the slides. Interpreters work in pairs on a full session so that one can take over while the other prepares the next stretch. A single interpreter suits only a short segment.

Consecutive work is face to face. The speaker talks for a stretch, stops, and the interpreter renders it. Notes, not a booth, carry the detail. The interpreter can ask for a missed name before delivering, which is harder in a booth while the speaker has already moved on. The cost of that control is time: the segment runs longer because the same content is spoken twice. Whispered interpretation, for one or two listeners, sits closer to simultaneous but without a proper feed. It is a short-term fix, not a format for a hall.

Effect on your programme length

Simultaneous interpretation leaves the published timings almost intact. A thirty-minute speech remains about thirty minutes for the audience. You still need a margin for a late start, but you do not double the speech. Consecutive interpretation does lengthen the spoken parts. A meeting that looks comfortable on a one-language agenda can run long once every stretch is repeated. Build that into the invitation, or cut the content until the day fits.

Panels are where people forget the rule. If four speakers answer in consecutive mode, the answers take longer than the questions suggested. Either shorten the number of questions or move that session to simultaneous. Do not solve it by asking the interpreter to summarise unless a summary was the brief. A summary is a different product from a faithful rendering, and it should be labelled as one.

Equipment differences

Simultaneous needs a system: floor microphones the booth can hear, a console, receivers and headsets, and a technician who stays. The booth needs a view of the stage or a camera feed. Consecutive needs a microphone the room can hear, a glass of water, and a speaker who will actually pause. It does not need a booth. Adding headsets “just in case” without a feed and a technician does not create simultaneous interpretation.

• Simultaneous: booth or quiet position, floor feed, headsets, a technician, interpreters in a pair for a full session.
• Consecutive: pauses agreed with the speakers, a room microphone, no booth.
• Both: the same agenda, name list and glossary, sent before the day.
• Neither replaces a host. The MC still runs the frame of the event.

Hotel ballrooms can be noisy at the back. If the booth is beside a service corridor, move it. If the consecutive meeting is a dinner, agree whether interpreting continues through the courses or stops when the speeches stop. Sound and cutlery are part of the format decision.

Which events suit a simultaneous interpreter

A simultaneous interpreter fits a plenary, a streamed session, or any programme whose clock cannot double. Conferences, large briefings and forums are the usual cases. Consecutive fits a board conversation, a negotiation, a classroom-sized workshop, a site visit, or a dinner speech where pausing is acceptable. The interpreters directory is where those roles are listed. If the event also needs someone to open, introduce and close, that person is a host, on the MC list, not a second interpreter.

Small meetings sometimes ask for simultaneous because it feels more formal. If the group is few enough to pause, consecutive is often the clearer format and the one that needs less equipment to go wrong. Large meetings sometimes ask for consecutive because nobody booked a booth. That choice only works if you are willing to cut the programme in half or lengthen the day.

Combining formats

A single day can use both. Simultaneous in the hall, consecutive in a breakout or on a tour, is a normal pattern. Write it on the run of show so the equipment arrives for the sessions that need it and does not sit unused in a room that will pause. Tell the speakers which mode they are in. A speaker who will not pause will break a consecutive session. A speaker who keeps stopping for a simultaneous booth slows a format that was meant to flow.

The host should know the mode too. Housekeeping can be said in both languages by the MC without becoming interpretation. The content of the speeches should not be. Give the interpreters and the host the same papers. Then send the split — which sessions, which languages, which rooms — in the request. The agency will confirm availability and propose a fee. It will be on request, because a simultaneous team with equipment is not the same brief as one consecutive meeting, and profiles do not publish rates or personal contacts.
