Vietnamese Subtitle Generator

• Auto captions that recognize Vietnamese by ear

  Upload a video and hit generate. Whisper-class speech recognition detects that the audio is Vietnamese without you picking a language first, then writes captions with word-level timestamps. If a clip mixes languages, a From-language override is available after transcription.

• A Vietnamese subtitle generator that respects the script

  Captions render the full chữ Quốc ngữ character set, including stacked forms like ế, ộ and ữ, so tone marks never come out clipped or floating. That matters in a language where má, mà and mạ are three different words. If you upload your own fonts through the brand kit, pick ones with Vietnamese glyph coverage and the marks stay crisp.

• 176 caption presets, karaoke styles included

  Style Vietnamese captions with 176 named presets, from clean broadcast looks to word-by-word karaoke fills where the active word lights up as it is spoken. Those karaoke styles land well with audiences raised on bouncing-ball lyric videos. Per-word color and emphasis editing lets you push a single word without restyling the line.

• Translate between Vietnamese and 85 other languages

  Caption Vietnamese speech and translate the text into English, Korean, Japanese or any of the 86 supported languages, or bring English subtitles into Vietnamese for the local market. Translation is a Pro feature. Translation rewrites the subtitle text only; the voice track stays as recorded. The subtitle translator covers the same flow for existing SRT files.

• Dual Vietnamese and English subtitles

  Show two languages at once, original on one line and translation on the other. Diaspora channels use it so grandparents and grandkids can follow the same upload, and English teachers in Vietnam use it for listening practice. See bilingual subtitles for the full walkthrough.

• Cue-by-cue editing for accents and slang

  Recognition copes with both Hanoi and Saigon speech, but regional vocabulary like ba versus bố can still slip through as the other region's term. Click any cue to retype it, split or merge cues, and drag timing on the timeline until each line lands with the voice.

• Burn it in free, or get SRT, VTT, TXT, JSON on paid plans

  Export the video with captions permanently burned in for TikTok and Reels, where most viewing happens with the sound off, or download the subtitle file for YouTube and Facebook uploads on a paid plan. You can also import an existing SRT or VTT file to retime or restyle it. Free exports are HD MP4 with a small removable badge.

• Edit the video from the transcript

  The transcript doubles as an editing surface: delete a sentence and the matching footage is cut, and filler sounds and long silences can be removed automatically. It is a quick way to tighten a talking-head clip before you caption it.

1. 1

   Upload your video

   Drag in MP4, MOV, WebM, MKV or any of the 20 accepted formats. Nothing to install; EchoWave runs in Chrome, Edge, Firefox and Safari.

2. 2

   Generate the subtitles

   Open the captions panel and click generate. Speech recognition detects the Vietnamese automatically, transcribes it, and lays word-timed cues onto the timeline. If detection guessed wrong on a mixed-language clip, switch the From language afterwards.

3. 3

   Proofread and style

   Scan the cues for names, brands and regional words, then pick one of 176 presets or build your own look with brand fonts and colors. With Pro, add a translated second line here if you want dual-language captions.

4. 4

   Export video or subtitle file

   Burn the captions in and download an MP4, free up to 720p with a small removable badge, 1080p and above on paid plans. Or skip the render and, on a paid plan, download SRT, VTT, TXT or JSON instead.

• Movie recap and review channels

  Review phim channels live on pacing, and burned-in captions keep viewers following with the sound off. Generate the base track automatically, then tighten cues to match your cuts.

• TikTok and Facebook creators in Vietnam

  Vietnam's feeds are mobile-first and mostly muted, so captions decide who keeps scrolling. Karaoke presets with active-word fill give skits and street food clips extra punch.

• Diaspora storytellers

  Families in California, Texas and Sydney watch with mixed fluency. Dual Vietnamese and English subtitles let a single upload serve both the grandparents and the kids.

• English teachers and learning channels

  English learning is one of Vietnam's biggest content niches. Caption the English speech, add a Vietnamese translation line underneath with Pro, and every lesson doubles as listening practice.

• Brands localizing into Vietnamese

  Vietnamese has roughly 100 million speakers and comparatively little localized content. With Pro, translate your existing English captions into Vietnamese and republish without reshooting a frame.

• Lyric and karaoke videos

  Word-timed cues are halfway to a lyric video already. Pair the karaoke caption presets with EchoWave's 93 music visualizer styles and a still image becomes a full music upload.
