Why Local Processing?

Keep your sensitive audio data on your own device.

View details

Local voice cloning keeps your audio data on your device. Unlike cloud-based services that require uploading your voice samples to a remote server, TTSBox processes everything in your browser.

The AI model is downloaded to your browser once and cached in IndexedDB. After that, all voice cloning and speech generation happens on your device's GPU via WebGPU.

This approach provides strong privacy guarantees, eliminates API costs, and enables offline use after the initial model download.
