Voice & audio
What it does
Combines the pieces of voice work that usually need separate services: reading text aloud, reproducing a specific voice from a few seconds of reference audio, and hold-a-key dictation into any text field. Everything runs on your own machine, so recordings and voice data never leave it. Seven speech engines and 23 languages are supported, with fifty-plus ready-made voices, and installers exist for macOS, Windows and Linux. Cloning someone's voice without their permission can amount to impersonation, so restrict it to your own voice or voices you have consent to use.
Summary based on the project's own description. The Japanese page has a fuller beginner guide: setup difficulty, what to prepare, and a step-by-step start.

Before you use someone else's face or voice
Recreating a person's face or voice without their informed consent, and publishing material that shows them saying or doing something they did not, can amount to defamation or a violation of personality and publicity rights, with civil and criminal consequences. Sexual content, or impersonation for financial gain, is treated far more seriously. Work only with your own likeness, or with material where the person has agreed to both the content and where it will appear. Running the tool locally protects your data - it does not make publishing the result lawful.
voicebox FAQ
- Is voicebox free?
- Yes. It runs on your own machine, so there is no usage-based cost either.
- Do I need to install anything or write code to use voicebox?
- You install it like a normal desktop app. No command line involved.
- Does voicebox work on a phone?
- No. It needs a computer.
- Can I use voicebox commercially?
- The licence is MIT, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
