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.
