First dub

On this page

1. Pick a language and voice

Open the Neko Dub popup, choose a Speaking Language, then pick a voice type under Speaking Engine:

  • Premium (default): a natural AI voice running on a GPU. By default Neko Dub sets up a free Google Colab for you, which takes about 3–5 minutes the first time.
  • Basic: a free voice with nothing to set up. Dubbing starts instantly, handy for a quick try.

2. Start dubbing

Open a YouTube video, click the Neko Dub button on the player controls → Start dubbing.

With a Premium voice on Colab, Neko Dub opens a Colab tab to prepare the server. Keep that tab open: dubbing starts on its own once the server is ready. See Try Colab.

3. Adjust while you watch

Click the Neko Dub button again to open the controls:

  • Dubbing Volume and Dub Offset (voice ahead of or behind the picture).
  • Subtitle size and position.
  • Translate: mute the dub and hear the original audio with translated subtitles. Click Dub to switch back.
  • Stop dubbing.

Don’t want to wait for Colab?

Colab is free, but every new tab means a 3–5 minute wait and a daily GPU limit. Two other options:

  • Try Modal: set up once, then it’s ready right away, with $30 free every month.
  • Your GPU: run it on a computer with an NVIDIA card.

FAQ

What if the video has no subtitles?

Neko Dub creates subtitles from the video’s audio with AI, which takes a while depending on the video’s length. Then you dub as usual. You need to be signed in, and it counts toward your plan’s AI hours.

Does dubbing cost anything?

The free plan dubs a number of videos per day, and both the Basic voice and the Premium voice on Colab cost nothing. Paid plans add more videos and features like multi-voice dubbing.
