What gets translated

A real Vietnamese version, not Czech with Vietnamese subtitles

Subtitling a Czech video leaves your Vietnamese audience reading while the Czech audio plays underneath. ngram builds an actual Vietnamese version: the Czech speech is transcribed and translated, a Vietnamese AI voice re-narrates it on the original timing, the captions are rebuilt in Vietnamese, and any Czech titles or lower thirds on screen are re-set in Vietnamese. Because Vietnamese stacks tone and vowel diacritics on almost every syllable, the captions are checked so those marks render cleanly instead of turning into boxes or dropped accents.

Both languages write in the Latin alphabet, but that is where the resemblance ends. Czech marks its sounds with the hacek and carka on letters like c, r, and e and inflects nouns across seven grammatical cases; Vietnamese carries its meaning in tone marks layered over the vowels. ngram translates the meaning rather than the letters, so a formal vy script for a manufacturing or B2B audience reads as natural Vietnamese, and you can pick a Northern or Southern voice on the way out.

Vietnamese AI voiceover

The narration is re-voiced in natural Vietnamese with accurate tonal delivery, timed to the Czech original.

Vietnamese captions

Captions are translated and re-timed, with Vietnamese tone and vowel marks rendered cleanly instead of dropped.

On-screen text

Czech titles, callouts, and lower thirds come out in Vietnamese, not left in the source language.

AI lip sync

Mouth movement adjusts to the Vietnamese voiceover so a talking-head cut still reads as native.

Why Vietnamese

Why Czech teams translate video into Vietnamese

Vietnam is a fast-growing export market and home to millions of speakers, and a large Vietnamese community lives and works in Czechia itself.

01

Reach the Vietnamese community in Czechia

Vietnamese is one of the largest minority languages spoken in the Czech Republic, and that community has run businesses and raised families there for decades. A Czech onboarding clip, retail training, or public-service notice becomes a Vietnamese version those residents follow in their first language instead of working through the Czech.

02

Sell into one of Asia's fastest-growing economies

Vietnam is one of Southeast Asia's fastest-growing digital economies, and Czech engineering and manufacturing exporters keep expanding there. A Czech product demo or installation walkthrough turns into a Vietnamese version for distributors and buyers in Hanoi or Ho Chi Minh City, with no second shoot to book.

03

Keep technical Czech scripts exact in Vietnamese

Clear Czech narration transcribes faithfully, so the specifications, part numbers, and step-by-step instructions in a training recording carry into the Vietnamese script intact. Teams working the Czech to Vietnam trade corridor hand local staff and partners a version they can act on, not a rough paraphrase.

How it works

Czech in, Vietnamese out, in four steps

01

Upload the Czech video

Drop in up to 1 minute of MP4, MOV, or WebM. Formal vy and casual ty Czech both transcribe, diacritics and all.

02

ngram transcribes and translates

The Czech audio is transcribed, then the script, captions, and on-screen text are translated into Vietnamese with full tone and vowel marks.

03

Review the Vietnamese version

Pick a Northern or Southern Vietnamese voice, check the tone marks, and keep the names, part numbers, and product terms the Czech-to-Vietnamese translation should preserve.

04

Export and publish

Export the Vietnamese cut for the channels, decks, and training portals where the Czech original could not go.
