Vietnamese AI voiceover for short videos

ainius makes short videos narrated by native Vietnamese AI voices: 8 native Vietnamese voices (Northern and Southern, male and female, news and TikTok styles) plus international voices. You give it a link, a topic or some text; ainius writes the narration, reads it in the voice you pick and builds a captioned video. Note that ainius makes new narrated videos; it does not dub a video you already have as it is.

The voices

  • Northern and Southern Vietnamese accents, male and female.
  • A news style (clear, even) and a TikTok style (faster, punchier), plus international voices for English videos.
  • On the Create screen, tap "Preview" to hear each voice before choosing. Changing the voice costs no extra credits.

Getting names right with the pronunciation dictionary

  • Add rules as "written" and "say it as", for example brand names, foreign names and abbreviations.
  • Available on every plan, including Free, up to 100 rules per account; you can preview 30 times a day.
  • Only the voice changes; captions and on-screen text keep the original spelling.

Making a narrated video

  1. Open ainius.net and paste an article link, type a topic, or tap "Paste the text instead" to paste text.
  2. Pick a voice, a length (30 or 60 seconds; 90 seconds from the Standard plan) and a caption style.
  3. ainius writes the narration, records the voiceover, picks visuals and adds captions; background music ducks under the voice.
  4. Review, download and post.

What ainius does not do yet

  • It does not dub a video you already have as it is. On the Medium model you can add 1 of your own videos (MP4, MOV or WEBM, up to 3 minutes, 200 MB) with the "Add video" chip: the AI cuts the best moments and mixes them with images in a new narrated video.
  • It does not export a separate audio file.
  • It does not read your text word for word: the AI condenses it into a narration that fits the video length.
