Q&A
FAQ
Translation engines are different. The automatic translation function included in Microsoft Office products uses Microsoft's translation engine only.
Human Science's MTrans for Office allows you to choose from DeepL, Google, Microsoft, OpenAI, and others.
It is also possible to connect a custom-trained engine (customization fees apply).
Additionally, the translation engines up to Office 2016 use an older method of automatic translation called "Statistical Machine Translation (SMT)."
With MTrans for Office, regardless of the Office version, you can use highly accurate "Neural Machine Translation (NMT)" powered by AI.
SMT is an automatic translation using statistics. Translation is achieved by processing a large number of pairs of original text and translated text through statistics.
NMT, also known as "AI translation," is a cutting-edge automatic translation technology that is currently attracting attention.
By using a neural network that mimics brain cells, the quality is significantly improved compared to SMT.
Although the engine does not have a learning function, the translation quality can be improved by using the glossary function.
It supports various languages.
The supported languages vary depending on the translation engine. Please refer to the following for a specific list of languages.
→Google
→Microsoft
→DeepL
→Amazon
→NAVER Papago
NMT currently only supports English language pairs.
For example, when translating from Japanese to Italian, it may be more accurate to translate through English, such as Japanese → English → Italian, rather than directly from Japanese to Italian.
You can check the usage status of each user.
Please contact us for specific details.
Translation accuracy may decrease if excessive font styles are set within a sentence. We are working to improve this, but for now, you can use the "Ignore formatting" feature as a workaround.
