How interpreters at the UN get the message across
Cuba's Fidel Castro spoke for more than four hours. Indian politician VK Krishna Menon was on the podium for more than eight. When delegates at the United Nations are faced with a runaway speaker, going far beyond the usual fifteen minutes or so, how do their live interpreters deal with the situation?
Not always well. The man who was interpreting the General Assembly speech by Libya's Colonel Muammar Gaddafi reportedly broke down towards the end of the 96-minute address. "I just can't take it any more," said Fouad Zlitni, according to the New York Post. Colonel Gaddafi had insisted on using his own translator rather than take advantage of an official simultaneous interpreter.
This week, leaders and representatives of the UN's 192 member states are gathering in New York to discuss key global issues, hoping that their messages, in all six official UN languages, will be faithfully delivered by a group of official interpreters. The Gaddafi incident is just one example of how taxing the job can become during big and unfolding events.
The thirty-minute rule
There is a reason Zlitni's collapse was predictable. UN interpreters do not work alone and they do not work long. They sit in pairs in a glass booth and swap roughly every twenty to thirty minutes, because the cognitive load of simultaneous interpretation is not something professionals push through by trying harder. The rotation is written into the standards of the International Association of Conference Interpreters, and it exists because accuracy falls off a cliff long before the interpreter feels finished.
Consider what the task involves. The interpreter listens to a sentence in one language while still speaking the previous sentence in another. They hold the incoming clause in working memory, restructure it for a grammar that may put the verb somewhere else entirely, choose a register, catch a number, catch a name, and produce fluent speech with a lag of a few seconds. All of this runs continuously, with no pause to think, for as long as the speaker keeps talking.
Ninety-six minutes of that, alone, without a partner to tag in, is not interpreting. It is endurance. Zlitni was not an official UN interpreter working to UN rotation rules. He was the delegation's own man, and the protection built into the system did not apply to him.
Six languages and a relay
The six official languages of the United Nations are Arabic, Chinese, English, French, Russian and Spanish. A speech delivered in any one of them can be interpreted directly into the other five. A speech delivered in anything else, and many are, has to travel through a relay: one booth renders the original into English or French, and the remaining booths work from that version rather than the source.
Relay adds a second or two of lag and, more importantly, a single point of failure. Whatever the pivot booth misses, every other language misses too. A delegation that supplies its own interpreter, as Gaddafi's did, is effectively volunteering to be that pivot.
What the booth needs before the speech starts
Interpreters are not walking dictionaries. They are prepared professionals, and the preparation is most of the job.
- Advance texts. Delegations submit speeches beforehand. Interpreters mark them up, verify names, check figures, and follow along line by line.
- Terminology. A single Security Council resolution can carry dozens of terms with fixed, negotiated translations. Getting one wrong is not a stylistic slip.
- Numbers and names. These are the hardest items to render live and the ones journalists quote, so they are prepared in advance wherever possible.
- A partner. The person in the next chair who takes over before concentration fails.
The system breaks in the same place every time: when the speaker abandons the prepared text. Castro was famous for it. Gaddafi tore up a copy of the UN Charter at the podium. The moment the paper stops matching the voice, the booth is working blind.
Beyond the glass booth
The same pressures shape interpreting everywhere, not just at Turtle Bay. Hospitals, courts and businesses run on interpreters who work under similar cognitive constraints with far less support. Remote modes such as phone interpreting have spread precisely because the alternative in most rooms is no interpreter at all, and because a qualified professional on a speakerphone beats an untrained bystander every time.
What professional interpreter services share, whether the client is a general assembly or an emergency department, is the discipline of the booth: render everything, add nothing, keep the register, and know when to hand over. A conference interpreter who works past their limit is not being heroic. They are producing worse output, and in a room where the output is the entire point, that is the only thing that matters.
The runaway speaker problem
So what happens when a head of state talks for four hours? The booths rotate. The pairs become shifts. Somebody in the back office rings the interpreters who thought their day was over. The delegates thin out, the cameras stay on, and the voice in the headphones keeps going, calm and unbroken, for as long as the man at the podium does.
Most of the time, nobody notices. That is what success sounds like. It is only when a lone interpreter, working without a partner for Colonel Gaddafi, says out loud that he cannot take it any more that anyone remembers there was a person in the booth at all.
