1. Define the languages and flows

Start by listing the languages spoken from the podium and the languages your audience needs to listen in. Plan one booth per listening language: an Arabic, French and English conference where everyone listens in their own language usually needs three booths. If part of the audience understands two of those languages, two booths may be enough.

The more precise you are here, the more accurate the quote: every extra booth means more interpreters and more equipment.

2. Plan the right number of interpreters

Simultaneous interpretation demands intense concentration. Professional standards call for two interpreters per booth once the working day goes beyond roughly half a day, so they can take turns every 20 to 30 minutes. A single interpreter over a full day means quality that drops by late morning.

3. Choose equipment that suits the venue

  • soundproof booths compliant with ISO 4043 for conferences held in a room;
  • interpreter consoles, a transmitter, and one receiver with headset per participant;
  • room sound (podium and discussion microphones) connected to the interpretation system;
  • a technician on site for the whole event;
  • for a site visit or a small group, a mobile kit with no booth (portable transmitter and receivers).

4. Send documents to the interpreters

Agenda, speaker list, presentations, written speeches, project glossary: everything interpreters receive in advance improves accuracy on the day, especially on technical topics. Send them as soon as they exist, even in draft.

5. Book early and test the day before

Good interpreters and equipment are in high demand during conference season. Book as soon as your dates are set. Booths are usually installed the day before or early on the morning of the event, and a sound check with the interpreters precedes the first session.

What drives the budget

  • the number of languages, and therefore booths and interpreters;
  • the duration (half day, full day, several days);
  • the number of participants, which sets the number of receivers;
  • the venue (Tunis or another city) and any travel;
  • the format: in person, hybrid or fully remote.
