Can AI Use a Person’s Voice or Face Legally?

Artificial intelligence has made it very easy to copy a person’s face, voice, expressions and style. Today, a person’s voice can be cloned within minutes, and a realistic video can be created even when that person never spoke those words. This raises an important legal question: can AI legally use a person’s voice or face?

The answer is not a simple yes or no. In most situations, the legal position depends on consent, purpose, manner of use, and impact of the use. If AI is used to copy or recreate a person’s identity without permission, the law may treat it as a violation of personality rights, privacy, dignity, reputation, or even as cheating and impersonation. If the use is authorised, limited, and lawful, it may be legally permissible.

This issue is becoming more serious because the human voice and face are no longer merely physical features. In the digital age, they are part of a person’s identity, image, commercial value and public presence. For celebrities, public figures and influencers, voice and face are often directly connected with endorsements, brand value and earning capacity. For ordinary individuals also, these features remain deeply connected with personal autonomy, consent and dignity.

Meaning of using a person’s voice or face through AI

When AI uses a person’s voice or face, it usually means one of the following:

• cloning a person’s voice so that new audio can be generated in that voice,
• creating a deepfake video using a person’s face,
• using facial likeness in an advertisement, video, app or platform,
• making a digital avatar that resembles a real person,
• recreating expressions, gestures, tone or speaking style in a way that clearly identifies that person.

In legal terms, this is not just the use of an image or sound. It is the use of identity attributes. A person is recognised not only by name, but also by face, voice, likeness and persona. Therefore, when AI copies these features, it may amount to use of that person’s identity itself.

Why the law treats voice and face seriously

A person’s face and voice are unique identifiers. They carry emotional, social and commercial significance. A face can suggest endorsement. A voice can create trust. A likeness can influence consumers. Because of this, unauthorised use can cause several kinds of harm.

First, it may make people believe that the person has supported, approved or promoted something. Second, it may damage reputation if the AI-generated material is offensive, false or misleading. Third, it may affect privacy, especially when the content is created without consent. Fourth, it may interfere with a person’s right to control how identity is used in public and commercial spaces.

This is why the legal discussion on AI-generated voice and face usually involves more than one branch of law. It may involve constitutional rights, intellectual property principles, tort law, cyber law, consumer deception and even criminal law in some situations.

Personality rights and right of publicity

The strongest legal idea in this area is personality rights, often linked with the right of publicity. Personality rights protect the commercial and personal interest of an individual in identity-related features such as name, image, likeness, voice, signature and other recognisable attributes.

In simple terms, personality rights mean that a person should be able to control the unauthorised commercial use of identity. If an AI tool uses a known person’s face or voice in advertisements, promotional materials, sponsored content or brand campaigns without permission, the law may treat that as an unlawful exploitation of personality.

This becomes even more important in relation to celebrities, public figures, artists, performers and influencers. Their voice and face are not merely personal features; they are valuable commercial assets. When AI copies them without permission, it can divert economic value and create false association.

At the same time, personality rights are not limited only to famous people. Even an ordinary individual has a legitimate interest in preventing misuse of identity, especially where dignity, privacy or deception is involved.

Link with Article 21: privacy, dignity and autonomy

In India, the legal basis for protecting a person’s voice and face is often connected with Article 21, which protects life and personal liberty. This includes the wider values of privacy, dignity, autonomy and control over one’s personhood.

A person’s face and voice are not detached from personality. They are part of bodily identity and individual presence. If AI takes these features and recreates them without consent, it may interfere with a person’s control over self-representation. Such interference is not merely technical misuse. It can become a question of dignity and personal freedom.

This is especially true when the content is intimate, false, humiliating, sexually explicit, defamatory or manipulative. In such cases, the problem is not only commercial misuse but also a direct attack on personal dignity and mental peace.

When AI use of voice or face may be legal

AI use of a person’s voice or face may be legal in some situations.

When there is valid consent

The safest legal basis is clear permission. If a person has agreed to the use of voice or face through a contract, licence, platform terms or recorded consent, the use may be lawful. However, consent should ideally be informed, specific and limited to a particular purpose.

For example, permission to record a voice for one project does not automatically mean permission to clone that voice for all future content. Similarly, permission to use a photograph once does not necessarily allow full AI-based replication in advertisements or commercial campaigns.

When the use is authorised for a legitimate project

Films, documentaries, dubbing work, gaming projects, memorial content or creative collaborations may involve lawful use if proper rights are obtained. In such situations, contractual clarity becomes very important.

When the use is not deceptive or exploitative

If a fictional AI-generated face or synthetic voice does not resemble any identifiable real person, legal issues become less serious. The main problem arises when an identifiable person is copied or imitated.

In limited cases of parody, satire or commentary

Some uses may be defended as satire, criticism or commentary. But this defence is not unlimited. If the content misleads the public, harms reputation, creates fake endorsement or becomes commercially exploitative, legal protection becomes weaker.

When AI use of voice or face may be illegal

In many situations, AI use of a person’s face or voice may clearly become unlawful.

No consent

If there is no permission, the use may violate personality rights or privacy. This is the most basic legal problem.

Commercial exploitation

Using AI-generated voice or face in advertisements, endorsements, product promotions, brand marketing or monetised content without authorisation is highly risky. This can amount to misappropriation of identity.

False endorsement and passing off

If AI makes it appear that a person supports a product, cause, service or political message, that can mislead the public. In such situations, the law may view the act in a manner similar to passing off, because the identity of the person is being used to create a false market association.

Deepfakes and reputational harm

If a false video or audio clip places words in a person’s mouth or shows conduct that never happened, legal consequences may arise through defamation, privacy claims and injunction-based remedies.

Impersonation, fraud and cheating

Where AI-cloned voice or face is used to deceive others, obtain money, manipulate family members, influence transactions or commit online fraud, cyber law and criminal law concerns become serious. Impersonation through technology can go far beyond civil wrongs and enter the area of cheating and personation.

Obscene or harmful content

Where a person’s face is inserted into explicit or objectionable content through AI, the violation becomes much more severe. Such use can affect dignity, mental well-being, social standing and safety.

Role of copyright, trademark and passing off

AI misuse of voice or face is often discussed together with copyright, trademark and passing off, but these are different legal ideas.

Copyright protects original works such as photographs, films, songs, scripts and recordings. It does not automatically protect a person’s face or identity as such. Therefore, even if copyright exists in a photograph or recording, a separate issue may still arise when a person’s likeness or voice is misused.

Trademark law may help when a name, signature, brand identifier or other distinctive commercial sign is registered or strongly associated with a person. This becomes relevant especially where celebrity identity functions as a brand.

Passing off is important when the misuse suggests false association, endorsement or approval. If AI-generated content makes the public believe that a famous person is connected with a product or campaign, a passing off claim may become relevant.

So, while copyright and trademark may help in some cases, they do not fully replace personality rights. AI-related disputes often require a broader identity-based approach.

Difference between celebrities and ordinary individuals

The legal discussion becomes more visible when celebrities are involved because their identity has market value. A celebrity’s voice or face can directly influence commercial decisions. Because of this, courts have shown willingness to protect celebrity identity against unauthorised use, including in situations involving modern digital misuse.

But the issue does not end there. Ordinary individuals also deserve protection. A non-celebrity may not have endorsement value in the commercial sense, but still has privacy, dignity and the right to prevent false impersonation. Deepfakes involving students, employees, private individuals or family members can be equally harmful, and in many cases even more damaging on a personal level.

Therefore, the law should not be understood as protecting only fame. It also protects personhood.

Importance of consent in the AI era

Consent is the central principle in this area. But in the AI era, consent must be understood carefully. It should answer questions such as:

• Was consent actually given?
• Was the person told that AI cloning or synthesis would happen?
• Was the consent limited to one use or many uses?
• Was the person informed of commercial exploitation?
• Can the content be edited, repurposed or resold?
• Is there a right to withdraw permission?

These questions matter because AI tools can endlessly reproduce and transform a person’s identity once the source data is collected. A casual recording or photograph can become the foundation for large-scale misuse. That is why a vague or blanket permission may not be enough in many situations.

Remedies available in such cases

If a person’s voice or face is used unlawfully through AI, several legal remedies may be considered.

Injunction

The most immediate remedy is to seek restraint on further publication, circulation, display or monetisation. In digital matters, speed is extremely important because fake content spreads fast.

Damages or compensation

If the misuse has caused economic loss, reputational harm or emotional injury, compensation may be claimed depending on the facts.

Takedown and platform action

Content may be reported to platforms for removal, especially where it is deceptive, harmful or non-consensual.

Defamation claim

If the AI content harms reputation by showing false conduct or false statements, defamation principles may apply.

Cyber or criminal complaint

Where the conduct amounts to cheating, personation, obscenity, harassment or fraud, criminal remedies may also be relevant.

The larger legal challenge

The law is still trying to catch up with AI. Earlier, misuse of identity usually needed professional editing or deliberate copying. Now, AI can produce highly realistic results at very low cost and high speed. This changes both the scale and the danger of misuse.

The central legal challenge is that AI blurs the line between imitation and reality. A face may look real, a voice may sound authentic, and yet neither may be genuine. This makes consent, disclosure and accountability even more important.

Conclusion

AI cannot freely use a person’s voice or face merely because the technology allows it. Legality depends mainly on permission, purpose and effect. Where there is informed consent and a lawful use, AI-based use may be valid. But where there is no consent, commercial exploitation, false endorsement, deepfake misuse, impersonation or reputational harm, the use is likely to be legally problematic.

In India, the legal response to such misuse can emerge through personality rights, the right of publicity, privacy, dignity, passing off, defamation and cyber law principles. The law increasingly recognises that voice and face are not ordinary data points. They are direct extensions of identity.

In the age of deepfakes and synthetic media, the basic legal principle remains simple: a person’s identity cannot be copied, commercialised or manipulated without lawful authority. AI may be powerful, but it does not remove the need for consent, dignity and accountability.
