Machine translation with human review

LinguaVox provides machine translation with human review for companies that need to process multilingual content efficiently while retaining professional control over meaning, terminology and usability. This service may be suitable for large volumes of repetitive or lower-risk content where machine translation output is good enough to edit productively. It is not a universal substitute for human translation, and it should not be used automatically for legal, medical, safety-critical, highly creative or formally sensitive documents.

Human review can mean different things, so the scope must be defined before work begins. Bilingual revision, monolingual editing, proofreading, light post-editing, full post-editing and final file checks are different services. LinguaVox distinguishes these workflows clearly so the client knows what level of intervention is being quoted and what the resulting text is intended for.

Full post-editing and ISO 18587

ISO 18587 applies specifically to full post-editing of machine translation. Full post-editing is a thorough human review intended to produce a result comparable to professional human translation for the agreed use. It addresses meaning, omissions, mistranslations, terminology, grammar, style, formatting issues and suitability for the target reader.

Light post-editing is different. It may make a text understandable for limited internal use, but it is not the same as full post-editing and should not be presented as an ISO 18587 workflow. For published, customer-facing or business-critical content, the quote should specify whether full post-editing, human translation with revision or another workflow is more appropriate.

When machine translation with human review can work

This approach is often useful for high-volume technical support articles, internal knowledge bases, repetitive product descriptions, certain ecommerce content, reference material, draft internal communications or large datasets where the source is clear and terminology is controlled. It works best when the language pair performs well, the content is structured and the client can provide glossaries, translation memories or style instructions.

It is less suitable for texts where nuance, liability, creativity or formal acceptance are central. Contracts, court documents, medical instructions, clinical content, patent claims, safety warnings, regulatory submissions, slogans and brand-sensitive copy usually require human translation from the outset or a more controlled specialist workflow.

The role of the post-editor

A post-editor is not simply correcting grammar. The linguist compares the machine output with the source and decides whether each sentence conveys the correct meaning, uses approved terminology and fits the intended audience. The post-editor may need to rewrite entire passages where the machine output is misleading, incomplete or unnatural.

Subject-matter expertise still matters. A machine-translated technical manual, legal policy or medical support article should be reviewed by a linguist familiar with the field. The machine output is a starting point, not a reliable first draft.

Workflow and quality checks

Before quoting, we review the source text, machine output if already available, language pair, file format, subject matter and intended use. If the output quality is too poor, we may recommend human translation instead. Where full post-editing is agreed, terminology resources, style instructions and translation memories are applied in the same way as in a professional translation workflow.

For higher-risk content, a second review can be added. Final checks cover formatting, placeholders, numbers, names, tags, terminology and delivery requirements. Responsibility for regulatory, legal or administrative compliance remains with the client or receiving body.

Related services

Machine translation with human review may connect with machine translation post-editing, translation memory and terminology management, technical translation services, website translation services and translation quality. For some files, human translation with ISO 17100 revision will be the better option.

How to request a quote

Send the source files, target languages, deadline, intended use, file format and any machine-translated output if it already exists. Include glossaries, previous translations, style instructions and examples of acceptable quality. We will confirm whether post-editing is realistic or whether another workflow is safer.

Difference from ordinary proofreading

Human review of machine translation is not the same as proofreading a human translation. The reviewer has to look for typical machine output problems: fluent but wrong sentences, missing negatives, inconsistent terminology, mistranslated units, incorrect names, false friends, awkward register and omissions that may not be obvious at first glance. A text can sound polished and still be wrong.

This is why the source text must normally be available. Reviewing only the target text may improve style, but it cannot confirm whether the machine output has preserved meaning. For business-critical content, a bilingual check against the source is essential.

Pricing and feasibility

Post-editing is not always cheaper than translation. If machine output is poor, inconsistent or unsuitable for the subject matter, correcting it may take as long as translating from scratch. Before confirming a quote, LinguaVox reviews the sample quality, language pair, content type, intended use and client expectations.

Where post-editing is suitable, the quote should define whether the client needs light review, full post-editing, bilingual revision after post-editing or final formatting checks. Each level has a different purpose and should be priced separately.
