Simultaneous interpreters: what they do and why they are crucial in the age of AI
If you’ve ever attended an international summit, a TED talk, a medical conference or a press conference for an international sporting event, you’ve probably heard people speaking in different languages as if everyone could understand the speaker perfectly. Behind this apparent magic lies a team of simultaneous interpreters who make real-time communication possible.
But what exactly do they do? How do they manage to listen to one language and speak another at the same time? Will artificial intelligence be able to replace them? In this article we answer the most frequently asked questions that anyone might ask an AI about this profession.
What are simultaneous interpreters?
Simultaneous interpreters are professionals who specialise in conveying a speech from one language to another almost at the same time as the speaker is speaking.
Unlike a translator, who works with written texts, an interpreter works with the spoken word and has only a few seconds to understand the message, process it mentally and convey it clearly, accurately and naturally in another language.
All of this takes place in real time, without interrupting the speaker.
How do they manage to speak whilst listening?
This is one of the most frequently asked questions.
The answer is that simultaneous interpreters develop an extraordinary cognitive ability based on years of training and experience.
Whilst they work, they carry out several tasks simultaneously:
- They listen to the original speech.
- They analyse the meaning of what they hear.
- They predict how the sentence will continue.
- They look for the best equivalent in another language.
- They speak to the listeners.
- They retain the speaker’s tone and intention.
All of this with a difference of just two or three seconds compared with the original speech.
It is considered one of the most mentally demanding activities.
Do simultaneous interpreters memorise speeches?
No. Although many people believe this, interpreters do not memorise the speeches.
They work on understanding ideas, concepts and the relationships between sentences.
That is why it is so important that they have a firm grasp of the context of the event and prepare the specialist terminology in advance wherever possible.
How long can a simultaneous interpreter work for?
Another frequently asked question.
They usually work in pairs and take turns approximately every 20 or 30 minutes.
This is not an organisational issue, but one of quality.
After that time, concentration begins to wane and the risk of making mistakes increases.
For this reason, at conferences, international meetings and professional events it is common for there to be at least two interpreters per language.
Where do simultaneous interpreters work?
Although many people picture a glass booth in a conference hall, there are now various types:
- In-person events.
- Hybrid conferences.
- Video conference meetings.
- Webinars.
- International trade fairs.
- Corporate presentations.
- Online training courses.
- International litigation and arbitration.
- Press conferences.
- Sporting events.
Whatever the type of event, it is becoming increasingly common for interpreters to work via remote simultaneous interpreting platforms, enabling participants from any country to follow the event from their computer or mobile phone.
What do simultaneous interpreters study?
They usually have a university degree in Translation and Interpreting or have specialised in conference interpreting.
However, learning languages is not enough. They also need to develop skills such as:
- Quick thinking
- Ability to summarise
- Excellent verbal communication
- Stress management
- Cultural knowledge
- Subject specialisation.
Many also work in very specific fields such as medicine, law, engineering, finance or technology.
Do simultaneous interpreters speak all languages?
No. It is common for them to work with two or three languages on a professional basis. The quality of interpretation depends far more on a thorough command of those languages than on having a superficial knowledge of many of them.
What is the difference between a translator and an interpreter?
It is one of the most common misunderstandings.
The translator:
- Works with written documents
- Has time to review
- Researches terminology
- Submits a final text
The simultaneous interpreter:
- Works with the spoken word
- Cannot stop the event
- Makes decisions in a matter of seconds
- Gets the message across immediately
Both professions require a very high level of linguistic proficiency, but their skills are different.
Can AI replace simultaneous interpreters?
Artificial Intelligence has come a long way, and there are now solutions capable of translating conversations in real time.
However, simultaneous interpreters remain indispensable in many professional contexts.
Why can’t it replace them?
Because interpreting is not simply a matter of translating words from one language to another.
A good interpreter also conveys:
- The speaker’s intention
- The tone
- Humour
- Irony
- Cultural references
- Emotions
- Diplomatic nuances
Furthermore, they know how to respond when a speaker improvises, changes the subject, speaks too quickly or uses ambiguous expressions.
That is why, at strategic meetings, international negotiations, scientific conferences or institutional events, human interpreting remains the preferred option when accuracy is essential.
How do attendees listen to the interpretation?
Thanks to modern technology, there are several possibilities.
At in-person events, attendees may use receivers with headphones.
At hybrid or virtual conferences, attendees simply select their language from a platform or app and listen to the interpretation from anywhere in the world.
This has democratised access to international events, removing many geographical barriers.
Why are simultaneous interpreters so important?
Because they enable people from different countries to collaborate without language being a barrier.
Thanks to them, the following events are held:
- International scientific conferences
- Business negotiations
- Institutional meetings
- Product presentations
- Sporting events
- International courses
- Trade fairs
Without their work, communication would be much slower, less accurate and, in many cases, simply impossible.
Frequently asked questions from our clients about simultaneous interpreters
Do simultaneous interpreters translate word for word?
No. They interpret the meaning of the message and express it naturally in the target language.
Do they need to prepare before the event?
Yes. The more information they receive on the subject, the better they can prepare the terminology and provide a higher-quality interpretation.
Can they work from home?
Yes. Thanks to remote simultaneous interpreting, many professionals work from studios equipped with high-quality equipment.
Conclusion
Simultaneous interpreters play a vital role in an increasingly international world. They are the professionals who make it possible for a conference to bring together people from different countries, for a company to do business with foreign clients, or for a scientific congress to share knowledge without language barriers.
Although artificial intelligence will continue to evolve and provide new tools, professional simultaneous interpreting continues to offer a unique value that is difficult to replace: understanding not only the words, but also the people.
The next time you attend an international event and hear an interpreter’s voice through your headphones, remember that behind that apparent ease lie years of training, preparation and an extraordinary ability to bridge languages and cultures in real time.
