Clone any voice with AI
Turn a few clean vocal clips into a reusable AI voice. Instant cloning gives you a zero-shot voice in seconds, while Best quality trains a dedicated model for the closest possible match — all in the browser, with nothing to install.
Already have a model? Import it straight from a Hugging Face or Google Drive link. Every voice you create lands in your library and the cover studio, ready to sing, rap, or narrate.

What is AI voice cloning?
Voice cloning builds a model of a voice from sample audio, so it can re-sing or re-speak anything you give it. On VoiceDub you can clone instantly from a clip, train a dedicated model for higher fidelity, or import a model you already have.
- Clone from as little as one clean clip
- Instant zero-shot voices in seconds
- Train a dedicated model for the closest match
- Import existing models from a link
- Use your voice across the whole studio
- No installs, plugins, or GPUs required
How to clone a voice
Instant clone or trained model
Two ways to clone — pick Instant clone or Best quality straight from the method picker at the top, and switch any time before you create.
What you can build
From cloning yourself to importing a community model, here’s what voice cloning unlocks.
Vocals or acoustics
Best quality comes in two forms in the method picker — Best · Voice and Best · Acoustics — so pick the one that matches your source.
The training controls, explained
On a Best-quality clone, flip the Simple/Advanced toggle to fine-tune how your model trains. (Instant clone has no settings to tune.)
- Isolate vocals
- Separates lead vocals from instrumentals so you can train from a full song. Turn off for raw, dry vocals.
- Smart training
- Stops automatically when quality peaks, so you don’t over- or under-train. Turn off to control limits yourself.
- Max minutes
- Caps how long training can run when Smart training is off.
- Max epochs
- Caps how many passes over your data the model can make when Smart training is off.
Already have a model? Import it
Choose “Use a link” to bring an existing voice model into VoiceDub without retraining.
What makes a great clone
The model is only as good as what you feed it — these four things move the needle most.

Put your voice to work
Once a voice is ready it appears in your library and the cover studio. Here’s what you can do with it.
Tips for the best clone
- Use clean, dry vocals with no background music for the sharpest clone.
- 30–60 seconds of varied singing or speech is plenty for an instant clone.
- For Best quality, leave Smart training on — it stops when quality peaks.
- Keep Isolate vocals on when your clips have any instrumental bleed.
- Pick Best · Acoustics to model an instrument or sound instead of a voice.
- Add a voice image so your model is easy to spot in the library later.

Voice cloning — frequently asked questions
How many audio clips do I need to clone a voice?
Just one clean clip works for an instant clone; up to five (200mb total) gives a trained model more to learn from.
What’s the difference between Instant clone and Best quality?
Instant clone is zero-shot — it’s ready in seconds and works for speech and singing. Best quality trains a dedicated model, which takes longer but sounds closer to the source.
Can I import a voice model I already have?
Yes. Choose “Use a link” and paste a Hugging Face or Google Drive link to a .pth file (or a .zip/.rar containing the .pth and .index files).
How long does training take?
Instant clones are ready in seconds. Trained models depend on your audio length and settings, but Smart training keeps it as short as possible.
What audio works best for cloning?
Clean, dry vocals with no background music. Keep Isolate vocals on if your clips have any instrumental bleed, and use a consistent single source.
What can I do with a cloned voice?
Once it’s ready it shows up in your voices and the cover studio — turn any song, YouTube/TikTok link, recording, or text into a cover in that voice.
Do I need a powerful computer or any installs?
No. Cloning runs entirely in your browser on any device — there’s nothing to download, install, or configure.
Whose voice am I allowed to clone?
Clone your own voice or voices you have permission to use. Don’t clone someone else’s voice without consent, and follow our Terms.
