A true Vietnamese cut, from Thai script to tone marks
Thai is written as an unbroken run of characters with no spaces between words, and vowels and tone marks stack above, below, before, and after each consonant. Before anything can be translated, that continuous string has to be segmented into words. ngram transcribes the Thai audio, splits the character run into words automatically, translates the script into Vietnamese, then rebuilds the captions and re-voices the narration on the original timing.
Vietnamese comes out in its Latin-based script, where a single vowel can carry both a quality mark and one of the tone diacritics that change the word's meaning. Captions are set so those stacked marks render cleanly instead of getting clipped, and the voice can be Northern or Southern Vietnamese to match who you are selling to. Thai politeness particles and register carry across, so a formal presentation stays formal in Vietnamese.
Vietnamese AI voiceover
The narration is re-voiced in natural Vietnamese with accurate tonal delivery, timed to your Thai original.
Vietnamese captions
Captions are translated and re-timed with the tone and vowel diacritics rendered cleanly rather than clipped.
On-screen text
Thai titles, callouts, and lower thirds are re-set in Vietnamese instead of left in the source script.
AI lip sync
Mouth movement adjusts to the Vietnamese voiceover so a talking-head shot still reads as native.
Why Thai teams translate video into Vietnamese
Vietnam is the next market down the Mekong, and Thai brands reach it by speaking Vietnamese, not by adding subtitles.
Reach one of Southeast Asia's fastest-growing markets
Vietnam is one of Southeast Asia's fastest-growing digital economies, and Thai brands, franchises, and manufacturers expanding along the Mekong corridor need their video to land in Vietnamese instead of playing in Thai with a caption strip.
Speak to viewers who scroll in Vietnamese
Vietnamese-language onboarding, support, and marketing video reaches teams and customers who rarely watch English content, so a Vietnamese cut of your Thai recording meets partners and buyers in the language they actually use every day.
Turn Thai tourism and product content into a Vietnam-ready cut
Thai creator, tourism, and factory-floor video already pulls regional audiences, and Vietnam is one of the biggest next door. A Vietnamese version opens that traffic without re-shooting the whole thing in a second country.
