Doubt and division echo throughout Hollywood and Silicon Valley as Scarlett Johansson and OpenAI dispute whether or not OpenAI’s now discontinued Sky voice—which the company launched last September—resembles Johansson’s actual voice.

Rijul Gupta, a synthetic media expert and the CEO of DeepMedia AI—a deepfake detection and AI security company based in San Francisco, California—shared a file exclusively with IT Brew showing no evidence of a voice match between Johansson’s real voice and Sky.


“This evidence suggests that it is very unlikely that OpenAI cloned Scarlett’s voice for use in their Sky voice demo,” he told IT Brew in an email. Deep Media—whose customers include major tech companies and the Department of Defense (DOD)—received a $1.25 million grant from the Air Force Research Laboratory to “integrate its tools” into DOD apps, Tech Brew reported last year.

“It is worth noting that DeepMedia’s Voice Biometric AI algorithms are unique in that they are trained on both real and synthetically generated voice samples, which we believe makes them more robust in use cases involving the comparison between real and GenAI voices such as this,” he wrote.
