Neural machine translation (NMT) looks at the entire sentence when translating, so the translation may change depending on surrounding words.
Registering a user dictionary should allow you to improve translation consistency to a certain degree. However, if too many common nouns are registered, the accuracy of the entire sentence might actually decrease, or the chance of unintentionally hitting partial matches might increase. You will need to be careful when selecting terms.
Also, if a sentence contains the following line feed symbols or notations in the middle, it will be considered to be a sentence break and may not be translated well.
Japanese to English
- Horizontal tabs
- Two or more consecutive spaces, line feeds
- For Word, PowerPoint, and PDF files, a single line feed will be considered as having split the sentence. However, line feeds within parentheses will not be considered as having split the sentence (a sentence break).
-
"．", "。 ", "！", "？", ".!?"
Exceptions: Situations where the character is in a word that has already been registered (such as "モーニング娘。" ), periods determined to be decimal points - For Excel files, a single line feed (Windows: Alt+Enter, macOS: Opt+Enter) in a cell will be considered as having split the sentence. Line feeds within parentheses will also be considered as having split the sentence.

Line feeds within parentheses will also be considered as having split the sentence.
Line feeds (including [Shift+Enter]) inserted in the middle of sentences to improve appearance (for layout adjustment) will also be considered as sentence breaks, as shown in the following examples.
