Frequently Asked Questions About Machine Translation Software
What is machine translation software?
Machine translation software reads text in one language and converts it into another automatically. You get translations handled by technology instead of leaning on a human translator for every word.
How accurate is machine translation?
Accuracy varies with the language pairs involved. For anything high-stakes, have a professional translator edit the machine output to tighten quality.
What are the types of machine translation technology?
There are four. Statistical Machine Translation (SMT) translates words verbatim, Rule-Based Machine Translation (RBMT) compares grammatical rules, Hybrid Machine Translation (HMT) combines the two, and Neural Machine Translation (NMT) uses artificial intelligence to learn a language the way a person would. NMT learns and translates most like a human.
Is machine translation cheaper than human translation?
Yes. Machine translation costs far less than hiring human translators, which is why you use it for high-volume work and bring a human in to edit the output.
How much faster is machine translation than a human translator?
Much faster. You translate large volumes of text in seconds, where a human translator would need days to cover the same amount.
Is there free machine translation software?
Yes. Microsoft Azure Translator, Google Cloud Translation, and Crowdin include free usage tiers, while Systran Translate and TextUnited give you a free trial.
Which machine translation software is best for enterprises?
Microsoft Azure Translator is our pick for enterprises with big data. If you are running large-scale, reach for Amazon Translate.
How do I choose machine translation software?
Match the tool to your needs. Weigh the language pairs you translate, whether you need enterprise-grade infrastructure like Azure or Amazon Translate, and whether you want built-in editing and glossary support to keep terminology consistent.
How can I improve machine translation results?
Do five things: have professional translators edit the output, pick translators with expertise in your industry, use Computer Automated Translation (CAT) software to hold translation memory, build brand-specific glossaries, and onboard your team before you deploy. Most errors trace back to wrong terminology, so glossaries matter most.
