Voice & audio
What it does
Reads text aloud with a controllable level of emotional intensity, and can imitate a supplied reference voice from a short clean sample. The model permits commercial use, so the audio can go into paid work. It is built for English and sounds unnatural in Japanese - Kokoro is the better choice there. Imitating someone's voice without clear permission can constitute impersonation; keep it to your own voice or one you have consent for.
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.
Chatterbox FAQ
- Do I need to install anything or write code to use Chatterbox?
- No install needed — it runs in the browser.
- Does Chatterbox work on a phone?
- No. It needs a computer.
- Can I use Chatterbox commercially?
- The project does not state a clear licence, so commercial use cannot be confirmed here. Check the official page or ask the author before using it at work.
