Simultaneous vs consecutive interpreting: choosing the right mode

Interpreting mode is not a preference; it decides the equipment, the number of interpreters and the length of the session. Choose it before you book.

Simultaneous

The interpreter speaks at almost the same time as the speaker, usually from a booth into headsets. The audience hears the original delivery, a second or two behind.

• Best for: conferences, large meetings, webinars, live events with many listeners.
• Needs: sound equipment, a booth or a quiet room for remote delivery, and at least two interpreters per language for a full day.
• Trade-off: highest setup cost, shortest delay for listeners.

Simultaneous interpreting is cognitively demanding. Sessions are normally staffed in pairs who take turns, which is why a full-day quote covers two people rather than one.

Consecutive

The interpreter speaks after the speaker, usually in short segments, rendering what was just said.

• Best for: smaller meetings, negotiations, site visits, one-to-one discussions.
• Needs: a speaker who pauses at natural points, and roughly double the time of the original discussion.
• Trade-off: no equipment, but meetings run longer.

Whispered (chuchotage)

The interpreter sits beside one or two listeners and whispers a live rendering. No equipment is involved.

• Best for: a single guest in an otherwise same-language meeting.
• Needs: close seating and a quiet room.
• Trade-off: impractical beyond two listeners, and hard on the interpreter's voice over long sessions.

Liaison and bilateral

The interpreter works both directions in a conversation — for example during a medical appointment, an interview or a supplier call.

• Best for: appointments, calls, interviews, community settings.
• Needs: short, clear turns from both sides.
• Trade-off: not suited to long monologues or documents read aloud.

Matching the mode to the room

| Setting | Usual choice | | --- | --- | | Conference or webinar with many listeners | Simultaneous | | Board meeting, negotiation, factory visit | Consecutive | | One guest in a same-language meeting | Whispered | | Appointment, interview, support call | Liaison |

Length and fatigue

Quality drops with duration. Plan breaks, and for a session longer than about 90 minutes of dense content, book two interpreters or split the session. On LingVata, sessions are stored in UTC and shown in your local time zone, and overlapping bookings for the same interpreter are rejected — so a long session is booked as one block rather than improvised on the day.

What to tell the interpreter in advance

Send the agenda, slide deck, names and any acronyms the day before. Ten minutes of context measurably improves terminology accuracy, and it costs nothing.
