Gemini 2.5 Flash Lite picks one of Korean's speech levels up front, because the ending on every verb in the passage depends on it.

Translating English to Korean
Korean speech levels are not politeness in the English sense - they are a grammatical system, and the ending of every verb depends on which one you are in. Choosing 합니다 over 해요 over 해 changes the entire passage, so consistency matters more than any individual word choice. Particles do the work English gives to word order: 은/는 marks topic, 이/가 marks subject, and the difference is real even though English collapses both into a plain subject. Word order is subject-object-verb like Japanese, but Korean uses a single alphabet, Hangul, rather than three scripts. Honorific verb forms shift depending on the listener rather than the subject. Echoo settles the speech level from your source register and keeps it.
Recommended Setup
Best model for this pair
Claude Sonnet 4.5 handles English to Korean best in our testing. Any provider you have configured will work - this is the one to pick if you have a choice.
Voice dictation
Dictation is supported for English, so you can speak instead of typing and have the result translated in the same step.
Tips for Better Translations
Korean has seven speech levels - specify formal (합쇼체), polite (해요체), or casual (해체) in your Echoo command.
Korean word order (SOV) differs fundamentally from English (SVO) - AI models restructure sentences naturally rather than translating word by word.
Konglish (Korean-English loanwords) may differ from direct translations - the AI uses natural Korean conventions.
For K-content or entertainment contexts, you can configure Echoo to use more contemporary, colloquial Korean.
