English → Japanese Translation Challenges
Every language pair has unique challenges. Here's how our AI handles the English to Japanese specifics.
Japanese Grammar & Structure
Subject-object-verb word order is opposite to English. Japanese frequently omits subjects when context makes them clear. Honorific register (casual, polite, humble, respectful) must match the content's audience. Katakana loanwords from English often have shifted meanings.
Japanese Pronunciation
Japanese uses a pitch-accent system (not stress-accent like English), where the pitch pattern determines meaning. Three writing systems (kanji, hiragana, katakana) mean TTS must handle mixed-script text. Honorific levels (keigo) dramatically change word choice and sentence structure.
