Clone your voice, step by step

This browser cannot run the voice model (it needs WebGPU, which phones do not have enough memory for). Open voice.demo on a laptop or desktop in Chrome or Edge for the full studio, see how it works, or connect your own private server below.
Where it runs
Before you start
In this browser, your recording and the cloned voice stay on this device: nothing is uploaded. With your own private server, they go only to that server.
1 · Record a sample
Read this out loud in a quiet room, about 15 seconds. The first sentence is your consent.
I'm recording my own voice for a private cloning test on this device. The quick brown fox jumps over the lazy dog, while five wizards box nimbly beside a quiet harbour. Clear speech, steady pace, no music in the background.
Progress
2 · Speak in the cloned voice
Keep it on this device
The voice model (about 800 MB) is saved in this browser after the first download, so next time it loads from your device. Ask the browser to keep it, and install voice.demo as an app.
