is currently in discussions with Scarlett Johansson's representatives following the removal of a voice that users found strikingly similar to the actress. This move comes after Johansson's legal team demanded transparency regarding the development process of the voice, named Sky.

Legal Demands and Public Reactions

Lawyers representing Johansson have sent two letters to OpenAI, seeking detailed information on how the AI assistant's voice was created. The actress's team has expressed concerns about the voice's resemblance to her character from the 2013 film “Her,” which has prompted a broader conversation about the ethical implications of AI-generated voices.

Joanne Jang, who leads model behavior at OpenAI, emphasized that the company is taking the feedback seriously and aims to clarify any misunderstandings. OpenAI has maintained that Sky's voice was not derived from Johansson's and has apologized for any confusion. The voice was removed from the default options after coverage highlighted the issue.

Development and Customization of AI Voices

OpenAI CEO had previously approached Johansson with a proposal to license her voice for the new ChatGPT assistant. “After much consideration and for personal reasons, I declined the offer,” Johansson said through a statement to NPR. Despite this, the company proceeded with a voice that many found eerily similar. CTO Mira Murati explained that the voice was developed from another actress's voice, whose identity remains undisclosed for privacy reasons.

Johansson says that OpenAI's decision left her “shocked, angered and in disbelief that Mr. Altman would pursue a voice that sounded so eerily similar to mine that my closest friends and news outlets could not tell the difference.”

Johansson has voiced her concerns about the broader issue of and the protection of personal likenesses. “In a time when we are all grappling with deepfakes and the protection of our own likeness, our own work, our own identities, I believe these are questions that deserve absolute clarity,” Johansson said.
