English to Vietnamese translator
English to Vietnamese translation with the register set first
Paste English and get Vietnamese back with the register set the way you want it. Vietnamese has no neutral 'you': people address each other with kinship terms chosen by relative age and status ('anh', 'chị', 'em', 'ông', 'bà'), and the speaker's own 'I' shifts to match. The selector decides the vocabulary and sentence shape before the translation is made, and any name or term you mark as kept is passed through untouched.
How to translate English to Vietnamese
Three steps. The second is the one most translators skip.
1
Paste or upload the English
Type, paste or drop in a document. English is already selected as the source on this page; if the text turns out to be something else, the detector says so above the editor and you can change it.
2
Set the register and mark the names to keep
Pick Formal or Informal from the register selector beside the language names, or leave it on Match source tone to follow the English original. Select any name, brand or product term and press Keep so it is passed through as written.
3
Translate, then check it
Read the Vietnamese if you can. If you cannot, back-translate it: run the result through Vietnamese to English and compare the meaning, sentence by sentence, with what you started from.
What changes between English and Vietnamese
The differences that decide whether a translation reads as written by a person.
Script and directionEnglish is written in Latin; Vietnamese in Latin with diacritics. Names cross between scripts by sound, which is why freezing them matters.
Word orderEnglish is subject-verb-object; Vietnamese is subject-verb-object. The orders match, which removes one whole class of error, but idiom and agreement still have to be handled.
How politeness is markedVietnamese has no neutral 'you': people address each other with kinship terms chosen by relative age and status ('anh', 'chị', 'em', 'ông', 'bà'), and the speaker's own 'I' shifts to match. Getting the pair right is the whole register.
Formality in EnglishEnglish has no separate polite and familiar 'you'. Register lives in vocabulary and sentence shape instead: 'Could you let me know' against 'Tell me', 'purchase' against 'buy'.
Where translation into Vietnamese goes wrong
Three things Vietnamese readers notice at once, and a machine has to be told about.
No neutral 'you'
There is no safe default for 'you'; a translation from English has to be told who is speaking to whom, and machines fall back on 'bạn', which is friendly but often wrong.
Tone marks are spelling
Diacritics mark tone and are part of spelling ('ma', 'má', 'mà', 'mã' are different words); text without them is ambiguous.
No tense or number
Vietnamese does not inflect for tense or number; time and plurality come from separate words that a translation must add deliberately.
What has to be read correctly in the English first
Errors that start on the source side, before a single Vietnamese word is chosen.
'You' is ambiguous
'You' is ambiguous: one person or several, a friend or a stranger. Translators guess, and a guess in the wrong direction is the single most common way an English original lands badly.
Stacked nouns
English piles up nouns ('customer data retention policy'); most languages need those unpacked into phrases, and a literal rendering is unreadable.
Phrasal verbs and idioms
Phrasal verbs ('put up with', 'look into') and idioms are translated word by word by weaker systems.

How does the register selector work for Vietnamese?
Vietnamese has no neutral 'you': people address each other with kinship terms chosen by relative age and status ('anh', 'chị', 'em', 'ông', 'bà'), and the speaker's own 'I' shifts to match. Getting the pair right is the whole register. The selector still matters: Formal produces the vocabulary and sentence shapes a Vietnamese reader expects in official or business writing, Informal the everyday ones, and Match source tone keeps whatever the English original was doing.
Will it translate names, brands and product terms?
Not unless you want it to. Select a name or a term in the editor and press Keep, and it is passed through exactly as written. This matters for English to Vietnamese because names are otherwise re-spelled in Latin with diacritics script by sound, and two runs can spell the same name two ways.
How accurate is machine translation from English to Vietnamese?
Good enough to understand a document, answer an email or draft a reply, and it improves when you set the register and mark the names as kept first. It is not a substitute for a human translator on a contract, a medical document or anything with legal weight. The reliable way to check a translation you cannot read is to back-translate it: paste the Vietnamese result into a new run set to English and see whether the meaning survived.
Can I translate a whole document from English to Vietnamese?
Yes. Drop in a .docx, .pdf or .txt file, or paste the text; the output keeps the paragraph structure and can be copied, edited in place or exported.
Can I translate Vietnamese to English as well?
Yes. Use the Vietnamese to English translator, or press the swap button between the two language names on this page. Either way the register and the kept terms come with you.
After the translation
Check the English before you translate it, or shift the register of the result once it is in Vietnamese. One plan covers every tool.
