How it works
How do you get Vietnamese subtitles from an English SRT?
Open the English SRT or VTT here; Vietnamese is the target already. Press Translate subtitles: neighbouring subtitles are translated together and each comes back in Vietnamese at its own time. Check the pronouns and names, then save the file.
- 1
Pick the file
Any .srt or .vtt whose language is on the From list; an English one is spotted automatically.
- 2
Translate into Vietnamese
Sentences that run over two subtitles are read as one and split back, one part per subtitle.
- 3
Save it
A .vi.srt or .vi.vtt, or a bilingual SRT with the English above the Vietnamese.
Do Vietnamese subtitles run longer than English ones?
A little. Vietnamese text runs slightly longer than the English it translates, on the same 42-character lines. Since each subtitle keeps its original time, a longer one gets two fuller lines rather than a third line or an extra subtitle.
How will the Vietnamese say “you”?
With bạn, the neutral word for a peer: “Bạn có thể gửi báo cáo cho tôi trước thứ Sáu không?”. “Sir” became ông: “Mời ông ngồi, thưa ông.”. Vietnamese picks pronouns by age and relationship, so a family video may need anh, chị, em or con instead.
The same goes for people spoken about. “Our doctor said she would call back tomorrow” became “… cô ấy sẽ gọi lại …”: cô suits a younger woman, while bà would fit an older doctor. Only you know which the video shows.
How are prices, dates and times written in Vietnamese subtitles?
The Vietnamese way: a decimal comma and a thousands point, “6,5 phần trăm” and “1.250 USD”, with the dollar sign spelled as USD. Dates read day, month, year, and the time kept a 12-hour clock: “lúc 3:30 chiều”, chiều meaning afternoon.
- The price went up by 6.5 percent to $1,250.
- VietnameseGiá đã tăng thêm 6,5 phần trăm lên mức 1.250 USD.
- The meeting is on October 16, 2026, at 3:30 p.m.
- VietnameseCuộc họp diễn ra vào ngày 16 tháng 10 năm 2026, lúc 3:30 chiều.
- Wow! That’s amazing!
- VietnameseOa! Thật là kinh ngạc!

What should you read before publishing Vietnamese subtitles?
Titles, two-syllable words at line ends, and pronouns. In our test “Dr. Patel” kept its English title rather than becoming Bác sĩ Patel, and one subtitle broke between phần and trăm, the two halves of “percent”. Both take seconds to fix.
Titles
Dr., Mr. or Ms. may stay in English; write Bác sĩ, ông or bà if that reads better.
Split words
A space falls between every syllable, so pull a word’s second half up if a break divides it.
Pronouns
Swap bạn, cô or ông for the forms that fit the people on screen.
Subtitling your own Vietnamese recordings?
Vietnamese is one of the languages NoteOwl understands on a Mac: it transcribes Vietnamese recordings with unlimited transcription, tells the speakers apart and saves SRT subtitles with their names. For subtitles of Vietnamese speech without translating, use the Vietnamese subtitle generator.
FAQ
Vietnamese subtitle translation: questions
Is it free to translate subtitles to Vietnamese?
Yes, with no sign-up: 3 files a day, and up to 30,000 characters of subtitle text in each.
Will letters like ư, ơ and ộ survive?
Yes. The translated file is saved as UTF-8, which keeps every Vietnamese letter and tone mark. If you edit it, save it as UTF-8 again so the marks stay intact.
Is the Vietnamese northern or southern?
It is standard written Vietnamese, which readers from Hanoi to Ho Chi Minh City use. Where north and south use different words, the translation picks one; adjust it for a regional audience.
How good is the Vietnamese translation?
In our test of 50 sentences, translation into Vietnamese scored clearly above the dedicated translation system we compared it with. Pronouns are the main thing to adjust for your viewers.
Can viewers see the English and the Vietnamese at once?
Yes. The bilingual SRT shows the original line above the Vietnamese one in each subtitle, at the same times, which suits language learners and bilingual families.
Does the timing change?
No. Numbers, start times and end times are copied from your file, and the number of subtitles stays the same.
Does my subtitle file leave my computer?
The file itself doesn’t: your browser reads it. Just the subtitle text is sent, batch by batch, to a cloud AI translation service that returns the Vietnamese and forgets the text. NoteOwl keeps no copy.
