Is Voicebox really free to use?

Yes, Voicebox is an open-source project and does not require any subscription or per-token fees. All generation happens on your own hardware.

What hardware do I need to run Voicebox?

It performs best with a GPU (NVIDIA with CUDA for Windows/Linux or Apple Silicon with Metal for Mac). It can run on a CPU, but generation will be significantly slower.

Does my audio data leave my computer?

No. Voicebox is designed as a local-first application. All voice cloning, text-to-speech synthesis, and transcriptions are processed entirely on your local machine.

Can I use it for long-form content like audiobooks?

Yes, Voicebox includes 'Unlimited Generation Length' by automatically splitting text into chunks and crossfading them for smooth, continuous audio.

How much audio do I need to clone a voice?

You can get high-quality results with just 5–30 seconds of clear reference audio. Multi-sample support allows you to add more clips to improve accuracy.

About Voicebox

What the tool does and who it's for

Voicebox is an open-source, local-first AI voice studio designed for high-fidelity voice cloning and text-to-speech without cloud dependency. Powered by the Qwen3-TTS engine, it allows users to replicate voices from short audio samples (as little as a few seconds) while maintaining complete privacy by running all processing on the user's hardware. The application features a comprehensive suite of tools, including a multi-voice timeline editor for stories and podcasts, post-processing audio effects via Spotify's Pedalboard, and Whisper-powered transcription. It supports multiple TTS engines like Chatterbox and TADA, offering capabilities ranging from expressive paralinguistic tags (laughs, sighs) to lightweight CPU-optimized inference.
