Frequently Asked Questions
What is technical translation and why is it important?
Technical translation is the specialized process of converting documents with industry-specific terminology from one language to another. It is critically important because errors in technical fields like law, finance, or engineering can lead to significant legal liabilities, compliance failures, and product malfunctions. Unlike general translation, technical translation demands absolute precision to ensure that complex documents are not only linguistically correct but also technically accurate in the target language.
How can I ensure consistency in technical translations?
You can ensure consistency by using tools with features like glossaries, style guides, and Translation Memory (TM). Professional CAT tools like RWS Trados Studio and MemoQ excel at this, allowing you to build a "single source of truth" with approved translations for recurring terms. A glossary defines key terminology, a style guide sets rules for tone and grammar, and a Translation Memory (TM) stores previously translated sentences to guarantee consistency across all documents.
Is machine translation good enough for technical documents?
Generic machine translation is often not sufficient for complex technical documents. However, advanced neural MT engines like DeepL provide a high-quality starting point. For the best results, use industry-specific AI translation, like that offered by Bluente, combined with human review (a process called MTPE). AI engines trained on specialized datasets (e.g., legal or financial documents) understand context and terminology far better than generic tools and deliver much higher accuracy.
What is the difference between a glossary and a translation memory (TM)?
A glossary is a list of specific terms and their approved translations, while a Translation Memory (TM) is a database of previously translated sentences or segments. A glossary acts as a project-specific dictionary to ensure key terms are used correctly. A TM stores full translated sentences, ensuring that entire phrases are translated consistently, which also speeds up the process and reduces costs.
How do you handle formatting in translated technical documents?
The best way to handle formatting is to use a modern translation platform like Bluente that automatically preserves the original layout. Manually reformatting translated documents is a major bottleneck that can introduce errors. Advanced translation solutions parse the source file, translate the text, and reconstruct the document with its original formatting, ensuring that complex tables, charts, and legal numbering remain perfectly intact.
When do I need a certified translation?
You need a certified translation when submitting official documents to government bodies, courts, universities, or for regulatory purposes. This type of translation includes a formal signed statement from the translator attesting to its accuracy. While a standard translation is for informational purposes, a certified translation provides a legal guarantee of accuracy that is essential for court evidence, immigration paperwork, or regulatory filings.
What role do human experts play in AI-powered translation?
Human experts are essential for verifying the technical accuracy and ensuring the natural fluency of AI-generated translations. The ideal workflow combines AI with two types of human experts: Subject Matter Experts (SMEs), who verify the technical correctness, and native-speaking linguists, who ensure the text is fluent, culturally appropriate, and reads naturally. This hybrid approach leverages the speed of AI with the precision and nuance of human expertise.
How can I translate confidential documents securely?
To translate confidential documents securely, use a professional translation platform designed for security, such as Bluente. Look for enterprise-grade features like end-to-end encryption, secure file handling, and automatic file deletion policies. Avoid public online translators, which may not protect your data. A secure platform ensures your information is protected and adheres to data privacy regulations, which is critical for sensitive legal, financial, or proprietary information.
