About Korean translation
Korean translation starts with a decision English never forces you to make
English gets by with one neutral «you» and a flat imperative. Korean doesn't have that option: every verb carries a speech level — 해요체 for everyday polite speech, 합쇼체 for formal or broadcast contexts, 반말 for close or younger audiences, among others — and the source text rarely states which one applies.
Choosing the wrong level isn't a stylistic nuance to fix later. It changes how the brand sounds: too casual reads as disrespectful or unprofessional, too formal reads as stiff or distant for a friendly audience. The decision has to be made before the first line is translated, because it sets the ending of every verb that follows.
At GoLocalise, we work with native Korean translators who fix the speech level from the brief, and every text is reviewed by a second linguist before delivery.

How can we help you?
Your project manager has everything covered
One point of contact from brief to delivery, and a second linguist on every text before it reaches you.
Brief review
We review your source material, your audience, and which Korean speech level fits your brand before a single line is translated.
Linguist assignment
Your project goes to a native Korean translator with experience in the relevant field and the agreed speech level.
Translation and review
The text is translated and then checked by a second native linguist for accuracy, consistency and the correct level throughout.
Delivery and consistency check
Files are delivered in the format you need, with the speech level applied consistently across every line.
Regional varieties
South Korea, and the wider Korean-speaking market
Korean is spoken natively by roughly 82 million people, mostly in South Korea and North Korea, plus sizeable communities in China, Japan and the United States.
Standard South Korean covers virtually all commercial, corporate and entertainment work, and it's the variety we use unless your project specifically requires otherwise. North Korean (Munhwaŏ) differs in vocabulary and register and is a separate, specialist request.

Areas of expertise
What we specialise in
From corporate video and eLearning to documentary, advertising and subtitles — always audiovisual, with the Korean speech level fixed before the first line is written.

eLearning and training video
Course modules and training films, speech level and terminology consistent across the programme.

Campaigns and short-form video, pitched at exactly the tone the target audience expects.
Subtitles and captions
Frame-accurate subtitles that hold the same speech level from the first line to the last.
Voice over and dubbing scripts
Scripts timed to the original, with the level fixed so the voice actor never has to guess.
Built for video and audio
Getting Korean right on screen
Korean forces a decision English scripts never make explicit, and getting it wrong changes how your brand comes across, not just how a line reads.
The speech level is set first, not fixed later
Every Korean verb ending encodes a level of formality — 해요체, 합쇼체, 반말 and others — and the source English rarely says which one is right. We agree it at the brief stage, because it shapes every sentence that follows.
Wrong level isn't a nuance, it's a tone problem
Too casual for a corporate audience reads as disrespectful or unprofessional; too formal for a young, friendly brand reads as cold and distant. Either one changes how the message lands, not just how it sounds.
Consistency across the whole script matters
A speech level that slips halfway through a video reads as a mistake to a Korean audience, so we hold it to a single level throughout, checked in review.
Timed, not dumped
What reaches you is a spotted subtitle file and a timed two-column script, not a text document still waiting to be cued.
Deliverables

Most common questions
How much does Korean translation cost?
Korean translation is priced per word for text and per minute for audiovisual, depending on volume, subject matter and turnaround, with agreeing the correct speech level included as part of the brief rather than billed as an extra step. Send your files and we'll come back with a free, itemised quote, backed by our Price Match Promise.
Are your Korean translations done by native linguists?
Yes. Native Korean linguists handle every translation, and a second native linguist independently reviews each text, fixing the speech level and register from the brief so the result reads naturally, sounds consistent, and lands correctly with your specific audience from the very first line of the script.
Do you provide Korean subtitling and voice over as well?
Yes — Korean translation, subtitling and voice over all come from one team, working to a single glossary and register throughout. The speech level is agreed with you up front and held consistent across every line, so subtitles and the voice-over performance never contradict each other in tone.
What are Korean speech levels, and why do they matter for our project?
Korean verb endings encode a level of formality — everyday polite, formal or casual, among others — that English simply doesn't mark. The source text rarely says which one applies, so it has to be decided before translation starts, not patched in afterwards, or the tone of the whole piece is wrong.
How do you decide the right speech level for our brand?
We look at your audience, industry and the tone of your existing English material at the brief stage. A corporate training video, a young lifestyle brand and a broadcast documentary each call for a different level, and getting it fixed early keeps every line consistent.
Do you deliver Korean subtitles and voice-over scripts, not just documents?
Yes — audiovisual is our specialisation. We deliver spotted SRT/VTT files and timed two-column voice-over scripts ready for the studio, and we also translate plain text and documents whenever a project calls for it, from corporate reports to marketing copy, technical material and eLearning courses.
What happens if the speech level is wrong?
It's not a minor style issue. A level that's too casual for a corporate or older audience reads as disrespectful or unprofessional, while one that's too formal for a young, friendly brand comes across as cold and distant. Either way, the message the words carry gets overshadowed by the tone problem, which is why we fix it before translation, not after.
Is North Korean the same language as South Korean?
They share a common origin but have diverged noticeably in vocabulary, loanwords and register over decades of separation, to the point that some everyday terms differ completely. Standard South Korean covers virtually all commercial, media and corporate work we handle; North Korean (Munhwaŏ) is a specialist, separate request we can arrange on demand.
How quickly can a Korean translation project be delivered?
Most short documents are delivered within 24 to 48 hours. Word count, subject complexity, and agreeing the right speech level upfront all move the delivery date, and your dedicated project manager will confirm a realistic timeline with you at the very start of the brief.
