1. Aren’t translators and interpreters the same?

This is a very, very common misconception. Outside of the language service provider sphere, “translator” and “interpreter” can be used interchangeably in most discussions. Such as: “We’ll need a translator at the board meeting” versus “We’ll need an interpreter at the board meeting.”

But just what is the difference between those terms? Simply enough, both “translator” and “interpreter” refer to someone who conveys information from one language to another; more specifically, a “translator” works with written words, while an “interpreter” works with spoken words. Some people are only translators, some are only interpreters, and others are both.

2. Can’t any bilingual person be a translator/interpreter?

A very common misconception (in the workplace especially) is “Billy is bilingual, so he can handle this project and translate/interpret for us.” Just because a person is bilingual (or trilingual or more, even), does not mean that they have the training required to be a proper translator or interpreter.

Imagine that “Billy” speaks Spanish at home, but grew up going to school where the primary language of instruction was English. While there’s a chance he can talk about any subject at home with his family members, a likely scenario is that he will know more about biology in English terms rather than Spanish terms. Unless the conversation were very simple, such as general conversation for travel or something similar, it would be very difficult for Billy to translate or interpret something.

Translators and interpreters go through rigorous training for their respective crafts, and have expanded their vocabularies enough to compensate. Proper translators and interpreters have high-level certifications as well.

3. I know a translator/interpreter who did Assignment X, why can’t they do Assignment Y?

In the language services industry, some translators and interpreters can fall under the category of “subject matter experts.” These people have trained to not just be general translators or interpreters, but have polished their skills to cater to certain types of work.

Take “Billy” from above, for example. Imagine he’s become passionate for being an interpreter, and his other interest in biology spurs him to an interest in medical interpretation. After enough study, focus, and—of course—certification, he becomes a proper medical interpreter and specializes in speaking between doctors and patients about surgeries. He might be able to do general interpretation as well, but because of his deep specialty, he might have trouble if he suddenly needed to interpret for, say, a lawyer discussing a lawsuit.

Just like how doctors and lawyers require separate studies, medical interpreters and legal interpreters also require focused study in their area of expertise. They may have skills that overlap, but generally, it’s best to rely on separate translators/interpreters who are subject matter experts rather than the same one for every single job.

4. Wouldn’t machine translation work well enough?

Short answer: No.

Long answer: Machine translation can certainly help a translator do their work. Computer-assisted translation tools (called CAT tools in the industry) can keep a handy glossary of terms for the translator, and have the memory to provide reference for older, similar translations.

But if we rely only on machine translation, any number of problems can happen. Machines think very differently than humans and might misinterpret context, homonyms, word register, and so on. Computers may be able to perform complex mathematical calculations, but the human brain is hardwired for language. Put simply, a translation from a human is going to sound a lot more natural—and have fewer mistakes—than a simple machine translation.

5. Why does a translation need proofreading? Shouldn’t the translator be enough for that?

Speaking of “mistakes,” mistakes happen. To err is human, after all. Translators need proofreaders for the same reason that a journalist, book writer, or a lawyer needs one. Mistakes concerning facts, grammar, spelling, etc. can easily be made by any sort of writer, and the same goes for a translator.

Having a second pair of eyes does wonders for any written work. A proofreader for a translation can catch errors in spelling, word register, a forgotten period or comma—anything that might have slipped through the cracks. If you want a translation to be as polished as possible, having a proofreader is essential.

At a conference, an English-speaker stands at the front of a table giving a speech in a normal presentation voice.  There are two interpreters seated near the speaker at the front on opposite sides of the table.  Each interpreter wearing a transmitter listens to what the speaker says and verbally translates it into Spanish and French in a softer volume, so as not to interfere with the speaker or each other.  Through the receivers the participants seated around the table hear the interpretation very clearly in their own languages, no matter how far away from the speaker they are seated.  The conference goes off without a hitch.

What is magic is that there are two languages being spoken, but people only hear their own languages.  If you do not wear a receiver, you will hear the dominant voice and the two softer voices in the background.  The interpreters, however, ingeniously stay focused and manage to perform two complex tasks at once.  It is an almost mystifying process.  Just as in Robert Altman’s movies there are many conversations going on at once but it is still clear what the focus is, the focus is very defined in this situation.

Unlike consecutive, which is a stop-and-go process, simultaneous interpretation happens concurrently with the speaker, which saves time.  All the while, the brain has to perform two processes at once: listening to the speaker, and then converting the speech into another language and speaking it at the same time.  Practically everyone can drive a car, but not everyone can simultaneously interpret a language, which requires training.

Simultaneous interpretation is the preferable form for conferences.  Interpreters have to go through training to acquire their skills.  Technology and interpretation equipment are also employed to assist in the process.  Interpreters work in pairs and take a break after a certain amount of time due to the concentration required.  In the process, interpreters might also have to interpret a speaker’s tone and emotions and convey the speaker’s personal style.  In that sense, interpretation is almost like a performance.  In the end, because of the thrill and excitement, an interpreter can feel like a singer does after the curtain call.
