AI Video Narration & Dubbing — Voice Over Any Video

Narration is the flagship feature of faceswap4fun: the AI listens to your video, translates it into the language you choose, and speaks the result over the film — fitted into the pauses so it never overlaps.

What is AI video narration?

You upload a video. The AI listens to the speech in it, translates it into the language you pick, and speaks the result over the film. What makes it different is the timing: each line is placed into the gaps where the film goes quiet, so the narration never overlaps itself and never cuts off mid-sentence. You get back a new video, spoken in your language, ready to download.

Languages you can narrate into

The "Narrate in" menu has five choices, and the voice list changes to match:

Narration languageVoices
Vietnamese40 voices
English10 voices
Korean4 voices
Chinese4 voices
Japanese4 voices

The film's original language (what the AI listens to) can be Vietnamese, English or Korean, or you can let it detect automatically. Chinese and Japanese work as the spoken-out language, not yet as the source.

What does it cost?

It is priced by the length of the video: 2.5 credits per minute (3.5 per minute for the higher-quality version). A four-minute film is about 10 credits. New accounts get 10 free credits, and you can preview the first 60 seconds for free before committing to the whole video.

How it works

  1. Upload your video.
  2. Pick the film's original language, or let it auto-detect.
  3. Choose the language to narrate into and a voice.
  4. Preview the first 60 seconds free.
  5. If you like it, render the full version and download. Results are kept for 12 hours.

Common questions

Does the narration overlap the original audio?
No. Each line is fitted into the film's natural pauses and is never cut off mid-sentence — that timing is the whole point of the feature.
How much does a full video cost?
2.5 credits per minute (3.5 for the higher-quality version), so a four-minute video is about 10 credits. New accounts start with 10 free credits and a free 60-second preview.
