Capital Linguists Translation Services

Human translation that helps your message make sense, wherever it needs to go.

Capital Linguists is an industry-leading provider of translation services in the US. Our human translators provide high-quality, expertly crafted translations of any document, surpassing your expectations, time after time.

Why Choose Capital Linguists For Translation Services

Capital Linguists combines human judgment with independently audited quality. Our translators are people with real language knowledge, cultural awareness, and relevant specialist experience, not an engine choosing the most likely next word. Each job is independently checked and coordinated by a project manager. We cover 200+ languages and dialects, including ASL and rare U.S. language varieties. We are open 24/7 for planned projects and genuine emergencies alike, and our confidentiality procedures are as careful as you would expect for sensitive legal, medical, financial, and government work.

Every Kind of Translation Under One Roof

From creative transcreation to technical publishing, our certified linguists cover the full spectrum of language work — so you never need a second vendor.

Localization Services: Help Your Content Feel at Home Anywhere

Content can be perfectly translated and still feel unnatural. We adapt the details around the language too, including local references, formats, terminology, and on-screen prompts, so your material feels natural wherever it’s destined.

Transcreation Services: Because “Accurate” Is Not Always Enough

For a legal document, literal accuracy matters most. For an ad campaign, the focus may be on the reaction it generates. Our transcreation linguists adapt creative content so it has the same purpose and impact in another language, even when the wording needs to change completely.

Multilingual Desktop Publishing: When the Words Change, So Does the Layout

Translation affects more than the text box, and you should not have to send translated copy back to your design team and start again. We’ll return your multilingual files so they’re properly formatted for the purpose, whether that’s print, web, presentations, packaging, or something else.

Subtitle Translation for Video Content

Subtitle translation is a different challenge from translating a transcript. It needs to fit the space on screen and match the pace of the video. We translate with the practical limits of the format in mind, including line length, timing, reading speed, and what is happening on screen.

MTPE (Machine Translation Post-Editing): When Software Produces the First Draft 

MTPE is a two-stage process. First, a machine translation tool creates the text, providing a rough starting point. Post-editing is the human stage that follows, revising and refining the output to create an accurate and clear result.

We Have Linguists Who Know Your Field

Our translators aren’t generalists guessing at terminology — they’re specialists who understand the standards, stakes, and vocabulary of your industry.

Legal Translation

Legal translation requires a unique combination of sensitivity, linguistic mastery, and legal expertise. We provide specialist legal services for court cases, business deals, internal investigations, and much more.

Medical Translation

We work on the written material used in healthcare settings, from patient records and discharge information to trial documents and product information. Projects are assigned to linguists with relevant medical experience.

Engineering Translation Services

From product manuals to manufacturing procedures, engineering translation needs to be clear and specific. We use linguists with relevant technical experience to translate materials for engineering, construction, and industrial clients.

Business Translation Services

There is no single “business document.” A board paper, staff handbook, investor update, and supplier brief all need a different approach. We translate the practical materials companies share internally and externally, with the reader in mind from the outset.

Marketing Translation Services

Marketing translation is not always about finding an exact equivalent. Sometimes a headline needs rewriting. Sometimes a joke needs replacing. Sometimes the original wording works perfectly well. We make those calls based on the market and the material.

Whatever You Need Translated, We Do It

You may have one certificate to translate, several hundred documents for a transaction, or a book that needs a careful literary voice. The work changes, but the need for a clear, dependable translation does not.

Document Translation

Forms, certificates, letters, reports, statements, old scans, phone photos—we see all of it. We work from the version you have and make sure the important information comes through clearly.

Medical Document Translation

Medical documents need a linguist with specialist knowledge, capable of handling the various abbreviations and terms that come with the field. We work with translators who are adept at working through records, results, consent forms, and other patient correspondence.

Business Document Translation

Sometimes it is a single urgent document that needs to be ready for tomorrow’s meeting. Other times, it’s an ongoing stream of files from different departments and offices. We translate the business materials that need to move between people who do not all work in the same language.

Anime Translation

Translating anime comes with its own unique challenges. For example, a character may speak differently depending on who they are with, a joke may only work in Japanese, and a translation needs to fit the physical constraints of the screen.

Book Translation

A translated book should not read as though several different people worked on it. We keep track of the language choices made early on, so character voices, terminology, style, and recurring references stay steady across the manuscript.

Frequently Asked Questions

Who do I speak to once the project is underway?

Your project manager is there to make the practical side easier. They will handle the scheduling and communication, so you know who to contact if you need an update or have something else to send over.

Do you use AI to translate documents?

Not for our standard translation service. Your document is translated by a qualified human linguist, then checked by another linguist before it is delivered. We do offer machine translation post-editing for suitable projects, but that is a separate service and is never used by default.

Can you handle technical or sensitive documents?

Yes. We work with legal, medical, financial, engineering, and other specialist material, assigning each project to a linguist with relevant experience. Files are handled under strict confidentiality procedures, with ISO 17100:2015 and ISO 9001:2015-certified processes supporting the work from request through to delivery.

My deadline is tight. Is it still worth asking?

Of course! We offer a rush service, although this does depend on the nature of the document and exact timescales involved. It’s always worth getting in touch, and we’ll see what is practically possible.

I need my documents to be translated into Spanish, but does it matter where it will be used?

It certainly can do. Spanish is a language with considerable regional variations, and this needs to be factored into a translation project. The best solution is to let us know the destination country or audience, and we’ll ensure the most appropriate variant is used.
