OpenAI Stole Scarlett Johansson’s Voice For ChatGPT-4o (“Sky”)

Actor Scarlett Johansson said in a statement shared with CNN on Monday that she was “shocked, angered and in disbelief” that OpenAI CEO Sam Altman would use a synthetic voice released with an update to ChatGPT “so eerily similar” to hers.

The statement comes after OpenAI said it is hitting the pause button on the update after comparisons with a fictional voice assistant portrayed in the quasi-dystopian film “Her” by Johansson.

The retreat by OpenAI follows a backlash to the artificial voice, known as Sky, which critics described as being overly familiar with users and sounded as if it had emerged from a male developer’s fantasy. It was widely mocked for its flirtatious tone.

“We’ve heard questions about how we chose the voices in ChatGPT, especially Sky,” OpenAI said in a post on social media Monday. “We are working to pause the use of Sky while we address them.”

Johansson said Altman offered to hire her last September to voice the ChatGPT 4.0 system. She said she declined the offer for “personal reasons.”

“Two days before the ChatGPT 4.0 demo was released, Mr. Altman contacted my agent, asking me to reconsider. Before we could connect, the system was out there.”

Johansson said she hired legal counsel, and said OpenAI “reluctantly agreed” to take down the “Sky” voice after her counsel sent Altman two letters.

“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. I look forward to resolution in the form of transparency and the passage of appropriate legislation to help ensure that individual rights are protected,” Johansson wrote.

The voice in question is not derived from Johansson’s, the company said in a blog post Sunday, but instead “belongs to a different professional actress using her own natural speaking voice.”

Altman reiterated the company’s stance that “Sky” was voiced by a different actress in a statement Monday, following Johansson’s claims.

“The voice of Sky is not Scarlett Johansson’s, and it was never intended to resemble hers,” Altman said. “We cast the voice actor behind Sky’s voice before any outreach to Ms. Johansson. Out of respect for Ms. Johansson, we have paused using Sky’s voice in our products. We are sorry to Ms. Johansson that we didn’t communicate better.”

OpenAI said that with each of its AI voices, it tried to create “an approachable voice that inspires trust,” one that contains a “rich tone” and is “natural and easy to listen to.” The ChatGPT voice mode that used the Sky voice had not yet been widely released, but videos from the product announcement and teasers of OpenAI employees speaking with it went viral online last week.

Some who heard Sky derided it as perhaps too easy to listen to. Last week, the controversy inspired a segment on The Daily Show in which senior correspondent Desi Lydic described Sky as a “Hot robot baby voice.”

“This is clearly programmed to feed dudes’ egos,” Lydic said. “You can really tell that a man built this tech.”
