A real Vietnamese version, not Japanese with Vietnamese subtitles
Subtitling a Japanese video leaves your Vietnamese audience reading while the Japanese audio plays underneath. ngram builds an actual Vietnamese version: the Japanese speech, across kanji and kana, is transcribed and translated, a Vietnamese AI voice re-narrates it on the original timing, the captions are rebuilt in Vietnamese, and any Japanese titles or lower thirds on screen are re-set in Vietnamese. Because Vietnamese is written in Latin script with stacked tone and vowel marks, the captions are rendered with fonts that keep every diacritic clean instead of clipping them.
It carries the register across, not just the words. A formal keigo script for a corporate briefing or an HR notice becomes appropriately polite Vietnamese, while a casual delivery stays relaxed. Northern Hanoi and southern Ho Chi Minh City Vietnamese are both available for the voice, so the output can match the region your Vietnamese viewers sit in.
Vietnamese AI voiceover
The narration is re-voiced in natural Vietnamese with accurate tones, timed to the Japanese original.
Vietnamese captions
Captions are translated and re-timed, with the full stack of Vietnamese tone and vowel marks rendered cleanly.
On-screen text
Japanese titles, callouts, and lower thirds come out in Vietnamese, not left in kanji and kana.
AI lip sync
Mouth movement adjusts to the Vietnamese voiceover so a talking-head cut still reads as native.
Why Japanese teams translate video into Vietnamese
Japanese manufacturers, employers, and brands run on the Japan-to-Vietnam corridor, and Vietnamese is the language that reaches the workforce at both ends of it.
Reach one of Southeast Asia's fastest-growing markets
Vietnam is one of Southeast Asia's fastest-growing digital economies, and Japanese manufacturers, electronics makers, and consumer brands have poured investment and plants into it. A Japanese product demo, brand video, or corporate update becomes usable for Vietnamese staff and customers without a re-shoot.
Train the Vietnamese floor in a language they follow
Vietnamese-language onboarding, safety, and support video reaches workers and customers who rarely consume English or Japanese content. Japanese corporate training and factory SOPs land on the plant floor in Vietnam when they arrive as a Vietnamese version, not a subtitled Japanese one.
Onboard Vietnamese technical interns in Japan
Japan hosts a large Vietnamese technical-intern and worker population, and HR, safety, and compliance briefings are recorded in polite keigo Japanese. ngram transcribes that keigo accurately and turns it into a Vietnamese version those workers can follow on day one.
