The honest answer is: at many conferences, yes, and at some, no. AI translation now follows most conference content well enough for the audience to understand everything that matters. But there are situations where a human interpreter brings judgment that no machine provides today, and where replacing them would be a real risk. The useful question is not whether AI is as good as a human in general. It is what kind of judgment your event requires.
We have already compared the budget side in SaaS translation vs human interpreters. This article leaves cost aside and looks only at quality: what a machine does well, what an interpreter does that a machine does not, and how to decide.
What an interpreter actually does
Interpreting is not translating word by word at high speed. A good interpreter listens to an idea, understands its intent, and rebuilds it in another language for a specific audience. They decide what to keep, what to make explicit and what to soften. When a speaker makes a joke that will not work in the other language, the interpreter may explain it, replace it or let it go. When a sentence is ambiguous, they choose the meaning that fits the context, or keep the ambiguity on purpose if it seems deliberate.
They also read the room. They notice when a speaker is being ironic, when a question is hostile, when a delegate is choosing words carefully to avoid a commitment. That awareness of intent, relationships and stakes is what we mean by judgment. It is the part of the job that is hardest to automate.
Where AI does the job well
Most of what is said at a conference is not diplomatic fencing. It is explaining, presenting, describing and arguing in a fairly direct way. On that kind of content, machine translation has become reliable.
Informational talks. A product presentation, a research talk, a training session or a panel on industry trends mostly carries facts and reasoning. The audience needs a faithful rendering of what is said, and that is exactly what a good system delivers.
Steady quality. A machine does not tire at the end of the day. The last session of the afternoon is translated with the same care as the opening keynote.
Many languages at once. Finding interpreters for rare language pairs can be difficult. A system like Glot covers more than 60 languages in parallel, so a participant who speaks a less common language is not left out.
Several formats. The same translation can reach people as a voice in their earphones, as captions on their phone, or as captions on the room screen. That helps participants who are hard of hearing, and those who simply prefer reading.
For these events, the audience rarely needs more. A small imprecision in a sentence about market trends costs nothing. What counts is that everyone follows the talk.
Where AI still falls short
The limits of AI are not mainly about vocabulary. They are about meaning that is not in the words.
Implicit meaning. Irony, understatement and polite formulas that mean the opposite of what they say are hard for a machine. It translates the sentence. The intent can get lost on the way.
Cultural nuance. Levels of politeness, indirect refusals, references to history or to local events often need adapting, not just translating. An interpreter knows when a literal rendering will sound rude or strange to the listener.
Confident mistakes. This is the most important point. When an interpreter is unsure, they know it. They can hedge, rephrase or flag the doubt. A machine produces a fluent sentence even when it has misunderstood, and the listener has no signal that something went wrong. In most contexts, that is a minor issue. In a negotiation, it can be serious.
Difficult sound. A human can often follow a speaker who steps away from the microphone, or two people talking over each other. Machine recognition depends on clean audio. Without it, quality drops quickly.
Responsibility. A professional interpreter answers for their work and usually follows a code of ethics, including confidentiality. With a machine, someone in your organisation has to take that responsibility.
Where a human remains essential
Diplomacy and politics. In an official meeting between governments or institutions, one word can change the meaning of a position. The difference between regretting and apologising is not a detail. These settings need interpreters who understand what is at stake.
Legal settings. Hearings, depositions, arbitration and contract negotiations produce statements that can have legal consequences. The rules of the procedure may also require a qualified interpreter. AI has no place as the main channel there.
Sensitive human moments. Testimonies of trauma, commemorations and religious ceremonies carry emotion that a synthetic voice cannot convey with the right weight.
Very high stakes. A board meeting about an acquisition, a crisis briefing, a negotiation where a misunderstanding cannot be undone. If one wrong sentence could cost far more than the interpretation itself, choose a human.
Combinations that work
The choice is rarely all or nothing. Many events can mix both approaches.
Split by session. Interpreters for the official opening or the high-level round table, AI for the breakout rooms, workshops and side sessions that no booth would cover anyway.
Split by language. Interpreters for the one or two main language pairs, AI for the other languages present in the audience.
AI alongside interpreters. Even when interpreters handle the main stage, live captions on the room screen and on phones help people who are hard of hearing. Some tools, Glot among them, also produce a written summary of the session at the end, which is useful for people who could not attend.
Human review afterwards. If a transcript or summary will be published, have a person who knows the subject check it first.
How to decide for your event
Three questions are usually enough. What happens if a sentence is slightly wrong: a small inconvenience, or a real consequence? Is the meaning mostly in the words, or between the lines? And what will the audience do with what they heard: understand and learn, or make a decision that commits them?
If a mistake is an inconvenience and the content is mostly informational, AI does the job, and does it for every language in the room. If a mistake is costly, irreversible or politically sensitive, a human interpreter is the right choice. And if your event has both kinds of moments, use both.
