This week Scarlett Johansson threatened legal action against OpenAI, the company behind ChatGPT. She contends that they asked her to provide voice samples to create a voice for ChatGPT. When she refused, OpenAI created a number of different voices that ChatGPT can use, hiring other actors and synthesizing an AI voice from their vocal samples. One of those voices, Sky, has no been taken down while OpenAI considers their next steps. She wasn’t the only one to note that the voice sounded a lot like her, drawing comparisons to her performance as an AI in the 2013 film Her.
But that doesn’t automatically mean that Johansson has a case. This is another example of how artificial intelligence has upended intellectual property, and how current law is being contorted to fit into a new framework in lieu of new legislation.
If none of Johansson’s actual performances were used, she would primarily rely on personality rights to bring an action. Personality rights exist at the largely at the state level, and not every state protects them. But California, where both OpenAI and Johansson reside, has some of the strongest protections. Personality rights protect the commercial use of one’s likeness, including identifiable features like one’s voice. If a company makes it seem like a celebrity has endorsed their product by using images or voice clips from that celebrity, they’ve likely violated their personality rights.
Personality rights extend to fake or impersonated voices as well. In Midler v. Ford, the Ninth Circuit found that Ford violated Bette Midler’s personality rights by hiring an impersonator to mimic her singing voice in a series of commercials. But here, OpenAI didn’t push claims that Johansson endorsed their product, and insisted it was not her voice. Even if they did make the voice sound like her performance in Her, it’s unclear whether this constitutes a violation of her personality rights. Personality rights never anticipated the speaking voice of an AI.
AI is changing the frontier of entertainment and intellectual property law. In doing so, it’s opening up new legal arguments that the courts will need to wrestle with.
