Voice models
VoxStudio's natural-sounding voices come from models, AI files that run on your computer. You download a model once, and from then on it works offline, as much as you like.
Open Models
Click Models in the sidebar (under More). At the top you'll see your computer at a glance: chip, memory and free disk space. VoxStudio uses these to tell you how well each model will run.

| Label | Meaning |
|---|---|
| 🟢 Great fit | Runs well on this computer |
| 🟡 Will run | Works, but may be slow alongside other apps |
| 🔴 Not supported | Not enough memory or disk space; the reason shows on hover |
| Recommended | A good first download |
| Apache-2.0 (etc.) | The model's license. Click it to read the terms. |
Download
- Click Download · 354 MB.
- A progress bar shows how much has arrived. You can leave the page; progress also shows in Activity in the toolbar.
- When it's done, you'll see Installed and a notification.
Your download is safe to interrupt. Cancel it, lose Wi-Fi or quit the app, and the next attempt resumes from where it stopped. Every file is checked against a known fingerprint (SHA-256) before it's used, so a corrupted download is never loaded.
Try and remove
- Try plays a short sample in the model's signature voice.
- Remove frees the disk space. Click it once, then again to confirm. Your takes are kept.
Use a model's voices
On Home, the Try a voice card now has a System | Kokoro switch. VoxStudio remembers the voice you last picked for each engine.
Available models
| Model | Voices | Languages | Size | License |
|---|---|---|---|---|
| Kokoro | 54 | English (US & UK), Spanish, French, Hindi, Italian, Japanese, Portuguese, Mandarin | 354 MB | Apache-2.0 |
| Chatterbox | Your own (voice cloning) | English | 3.2 GB + 1.3 GB engine | MIT |
| Whisper Base / Small / Large v3 Turbo | (speech recognition) | ~99 languages | 145 MB / 484 MB / 1.6 GB + 260 MB engine | MIT |
Chatterbox brings its own engine (PyTorch), installed in a separate, isolated space so it can't interfere with anything else. Removing Chatterbox removes that too.
For IT teams: offline installs
Set the VOXD_MODEL_MIRROR environment variable to serve model files from your own network. See Models API → mirrors.
