To reduce interpretation costs without losing your international audience, stop treating every session and every language the same way. Match your language list to the people who actually registered. Keep human interpreters for the few moments where nuance carries real risk, and use live AI translation for the rest. Then remove the hardware that quietly inflates the bill: booths, headsets and the technicians who run them.
Why interpretation budgets grow so fast
Simultaneous interpretation is organized per language and per day, and almost every cost multiplies. Interpreters usually work in pairs and take turns, because listening and speaking at the same time is exhausting. Each language needs its own pair, a booth and a technician to manage the sound. Headsets must be rented, handed out, collected and counted. Interpreters are often booked weeks in advance, which means you commit to a language list before you know who is coming.
None of this is waste. It is what good human interpretation requires. The problem is applying that full setup by default, to every room and every language, when the event does not need it everywhere.
Choose languages from registrations, not assumptions
The most expensive language is the one nobody listens to. Many organizers pick their languages early, based on the countries they hope to attract. Then the event happens and some channels serve a handful of people.
Add a language question to your registration form and read the answers before you commit. You will often find that a few languages cover most of the room, and that others are requested by very few attendees. With human interpreters, each extra language means a new team, so this decision has a direct effect on cost. With AI translation the trade-off changes. With Glot, for example, more than 60 languages are included in the price, so adding a language for a small group costs nothing extra. Instead of cutting the long tail of your audience, you can serve it.
Keep human interpreters for high-stakes moments
Not every session carries the same risk. A speech by a minister, a press conference, a negotiation or a legal session can justify a professional interpreter. A badly chosen word there can have real consequences, and an experienced interpreter brings judgment on tone, courtesy and context that software does not fully match yet.
Most of a program is different. Panels, product talks, workshops and breakout sessions are about sharing information clearly. The audience needs to follow the ideas, not to receive a diplomatic rendering of every phrase.
Go through your agenda session by session and ask one question: what happens if a sentence is translated a little less elegantly? If the answer is "nothing serious", that session is a candidate for AI translation. If the answer involves contracts, reputation or politics, keep the interpreters there. This split usually concentrates the human budget on a short part of the program, where it does the most good.
Use live AI translation for the rest
Live AI translation listens to the speaker, transcribes the speech and translates it as it goes. Attendees follow on their own phones. On Glot, they scan a QR code and open the translation in their browser, with no app to install and no account to create. The delay is about two seconds, which keeps the translation close to what is happening on stage.
Setup is light. The sound can come from the room's mixing desk, a wireless lavalier microphone or a USB table microphone, and a room can be ready in a few minutes. That matters as much as the price itself, because it removes the planning time, the briefings with interpreter teams and the need for a specialist AV crew in every room.
AI translation also brings things interpretation usually does not. It can tell speakers apart and show who is talking, display captions on the room screen, and produce a written summary of the session at the end. Attendees who prefer to hear the original speaker can still listen to the original sound.
Choose captions over voice when captions are enough
A translated voice feels closest to interpretation, and for long talks or audiences who prefer to listen, it is the right choice. But many sessions work just as well with live captions in each attendee's language. Technical talks, sessions full of product names and audiences who read a language better than they hear it often do well with text.
Captions also cost less. Public prices per room, for up to 300 attendees, show the gap. The Captions plan is 235 € per day or 40 € per hour. The Voice plan, which adds a natural translated voice, is 590 € per day or 99 € per hour. Mixing the two by session, voice for the plenary and captions for the workshops, is a simple way to lower the total without leaving anyone out. Hour credits are degressive and valid for 12 months, which suits organizations that run short sessions spread over the year. Above 300 attendees per room, pricing is on quote. The details are on the pricing page.
Remove booths and headsets
Hardware is the part of the budget people forget to question. Booths must be delivered, built, soundproofed and taken down. Headsets must be rented, charged, cleaned, distributed and collected, and some always go missing. Each item adds staff time and a line on the AV quote.
When attendees follow on their own phones, most of that disappears. There is no queue at a headset desk, no deposit to manage and no booth taking up space at the back of the room. Attendees who want to listen to the translated voice simply use their own earphones.
What you should not cut
Saving money should not mean a worse experience for the people who travelled to attend. Three things are worth protecting.
Sound quality. Any translation, human or AI, depends on a clean signal. A good microphone for every speaker matters more than almost anything else.
Clear instructions. Put the QR code on the screen and on printed signs at the entrance, so attendees know how to follow before the first talk starts.
A short test. Run one before the event with the real setup, to catch names, acronyms and room noise early.
A simple plan for your next event
Start with registrations and list the languages people actually asked for. Mark the sessions where a translation error would have real consequences and keep professional interpreters there. Move the rest of the program to live AI translation. For each of those sessions, decide whether captions are enough or whether a translated voice is worth it. Then remove the booths and headsets you no longer need.
The result is not a cheaper copy of the same event. It is an event where every language you offer is one people use, where the human budget goes to the moments that need it, and where every attendee can follow on the phone already in their pocket.
