One person, one microphone, one direction — that is the format every translation setup is demonstrated with, and it is the format your most valuable sessions are not in. Panels, interviews and open Q&A are where a room actually decides things, and they are structurally harder.
The good news is that almost every fix is a chairing fix rather than a technical one, and every one of them improves the session for the people in the room too.
Why overlap breaks it
When two people speak at once, the microphone receives one blended signal, and there is no clean way to split it back into two speakers. A human interpreter in this situation picks one voice and drops the other, and will usually say so. A system does something similar, less gracefully and without telling anyone.
The result is not a mistranslation so much as a missing half — and, worse, a missing half that reads as though it were complete. Somebody following on a phone has no way to know that two people were talking.
This is not solvable with better technology. It is solvable with a chair who interrupts.
The microphone rule that fixes most of it
One live microphone at a time.
If you have four panellists and four open microphones, you are broadcasting the sum of four people — plus the chairs creaking, plus the person turning pages, plus the panellist agreeing under their breath. Every open microphone adds room noise whether or not anyone is speaking into it.
Either mute what is not in use, or hand one microphone along the row. The passing itself enforces turn-taking better than any request from the chair, and it is visible to the audience, which makes the discipline feel like part of the format rather than a rebuke.
Repeat the audience question. Always.
This is the single most common failure at every conference, in every language, in every country.
The question comes from row twelve without a microphone. The panel answers. Every listener not within a few metres of row twelve hears an answer to nothing — including everyone reading on a phone, everyone on the live stream, everyone who will ever read the transcript, and the hard-of-hearing members sitting three rows away.
Either run a roving microphone, or make it the chair's job to repeat every question before anyone answers. The second option costs nothing, requires no equipment, and never fails. It also gives the panel five seconds to think, which they will thank you for.
Name the speaker
Subtitles arrive as a stream of text with no face attached. In a monologue that is fine. In a panel, a reader cannot tell who is talking, and a disagreement becomes genuinely incomprehensible — two contradictory statements in a row, apparently from the same person.
"Maria, what do you think?" solves it entirely, and good chairs do it anyway. Ask panellists to do the same when they respond to each other: "I'd disagree with Anna there" tells the reader who is speaking and who is being answered, in five words.
Pace, and the trap of the fast panel
A lively panel is a good panel, and it is also the hardest possible material. Short exchanges, interruptions, half-sentences, laughter over the top of an answer.
You cannot ask people to be dull. What you can do is build in the pauses that would exist anyway: a beat between speakers, a clean handover, and the chair summarising briefly before moving to the next question. Those three habits cost about ninety seconds across an hour and they change the transcript completely.
Give the chair a script
- Repeat every audience question into the microphone.
- Name the person you are handing to.
- Cut across overlap immediately — "hold on, let Anna finish".
- Pause a beat between speakers rather than overlapping the handover.
- Summarise before moving on, in one sentence.
Print it on a card and put it on the chair's table. Chairs are usually glad of it — these are the things they meant to do anyway and forget under pressure.
Warn the panellists once
Thirty seconds before the session: there is live translation, so one voice at a time, and let the chair repeat the questions.
Panellists comply readily when they know why. What does not work is asking them mid-session, which sounds like a criticism in front of an audience — and what really does not work is not telling them at all and hoping.
If a panellist has a strong accent or speaks very fast, do not single them out. Fix the microphone instead: a close, well-placed microphone does more for a difficult voice than any request to slow down, and it costs nobody any dignity.
What to accept
Set expectations honestly with organisers. A well-chaired panel translates well. A free-for-all does not, and no product claim should convince you otherwise. If the session is genuinely a scrum by design — a debate, a rapid-fire format — say in advance that the translation will be partial, and consider whether the transcript is worth keeping at all.
It is better to under-promise on one session than to have an audience conclude the whole thing is unreliable.
Where it matters most
The formats worth translating most carefully are the ones where people ask things — the members' meeting, the open forum, the interview, the session after the main talk where the real questions come out.
That is where language barriers cost real decisions rather than merely comprehension, which we wrote about in members' meetings and the room where language barriers cost the most.
