Machine Translation
Post-Editing (MTPE) Services for Business

What Is Machine Translation Post-Editing (MTPE)?

Machine translation post-editing (MTPE) is the professional process of reviewing, correcting, and improving text that was initially translated by a machine translation engine or AI tool — such as DeepL, Google Translate, ChatGPT, Amazon Translate, or another LLM — to meet the quality standard required for business or public use.

It is a hybrid process - a human editor with expertise in the subject matter and both languages works through the MT output systematically: correcting mistranslations, fixing terminology, improving fluency, resolving cultural errors, and ensuring consistency. The result is content that reads like it was professionally translated — because it was, at least in the final mile. MTPE is the human expertise applied after the machine. It is still a fundamentally human service — and it is exactly the kind of service that demonstrates why human linguistic judgment cannot be automated.

How Machine Translation Post-Editing Service Helps Businesses to Grow Faster at Lower Cost

Technological advancements have affected and positively influenced many areas of our lives, both personal and business. The best way to move your company forward is to combine the power of technology with human capabilities. That’s exactly what TheWordPoint's machine translation post-editing service does. Our MTPE service begins by using a machine to translate the given text. Once we have the translation, human editors take over. They carefully review the text and improve it to provide an above-average translation output. You get top-quality translations faster and at a lower cost! Why Is MTPE Important for Your Business?

Your company’s goal is to expand to different international markets. The best way to communicate with the local audience is in their native language. MTPE helps you convey the right message and enter the market as soon as possible by offering a mixture of software and human translation service options. MTPE will take care of your translation quickly. Human post-editors are there to secure quality improvement and give the translation that extra touch that makes it unique. They review the text to enhance readability and adapt it to the native language and cultural nuances. The result is a top-quality translation in the shortest possible timeframe.

How MTPE Can Speed Up the Translation Process and Decrease Your Expenses for Translation

Our editors prepare the text and run it through reliable automatic software that can translate to 80+ languages. Machine translation only takes seconds to deliver results, which is an incredible time saver. We use advanced translation engines where algorithms have a comprehensive set of models and patterns that generate the result.

The next step is for a human translator to take over. Depending on our arrangement, the post-editor can look only for obvious spelling and grammar errors. A complete machine translation post-editing process guarantees that the translator reviews each sentence carefully. They edit it while considering consistency, your brand’s tone, and target language specifics. Either way, you receive the results more quickly than with manual translations. Our experts guarantee delivery within the promised deadline. At TheWordPoint, we are proud of our machine translation post-editing rates being affordable and accessible to anyone. With MTPE, the entire process is shorter. The machine does the first part by translating the text, so there’s no need for a human translator to spend hours or days on it. Our staff will review the text to offer contextual understanding and use suitable phrases for the target market and niche.

Light Post-Editing vs Full Post-Editing — Which Level Do You Need?

Light Post-Editing (LPE) The post-editor corrects only errors that affect meaning: mistranslations, missing or added content, incorrect terminology, and serious grammar errors that impede comprehension. Style issues, minor fluency problems, and non-essential grammar corrections are left as-is.

Appropriate for: Internal communications, knowledge base articles, FAQs, product data sheets, large-volume content with limited public exposure, gisting (understanding general meaning rather than publication quality).

Not appropriate for: Customer-facing copy, marketing materials, legal documents, published content, anything with brand voice requirements.

Full Post-Editing (FPE) The post-editor brings the MT output to the same quality standard as a professionally produced human translation. All errors in accuracy, grammar, style, fluency, terminology, cultural appropriateness, and formatting are corrected.

Appropriate for: All customer-facing content, marketing and advertising copy, legal and regulatory documents, published articles and communications, product interfaces, anything seen by external audiences.

Our recommendation: If you are unsure which level you need, default to full post-editing for any content visible to customers or partners. If you have a large volume of internal or support content, light post-editing is cost-effective. Our project team will advise based on your specific content type and intended audience.

When to Use MTPE — and When Human Translation Is Required

This is the most important decision a localization manager or content team faces. Use this guide to determine the right approach for your content:

Use MTPE when:

• Volume is high and per-unit cost reduction is a priority
• Content has limited public exposure (internal documentation, support articles, product data, internal communications)
• MT output quality is already reasonable for your language pair (European pairs typically perform well; rare language pairs require more editing or full human translation)
• Turnaround time is critical and full human translation timelines are too long
• You have existing translation memory and terminology assets that help the MT engine produce consistent output
• Content is technical and structured, where accuracy matters more than fluency

Use full human translation when:

• Content is customer-facing and brand voice must be precisely maintained
• Subject matter is legal, medical, or regulatory (legal liability attaches to errors)
• Content will be certified for official institutional submission (USCIS, courts, academic institutions require certified translation — MTPE does not produce certified translations)
• The language pair has poor MT performance (rare pairs, non-Latin script languages with complex morphology — Arabic, Japanese, Chinese, Finnish, Hungarian, Turkish)
• Creative, marketing, or advertising content where cultural nuance is the product
• The document will be seen by senior executives, clients, regulatory bodies, or any audience where a translation error has significant consequences
