As are disclaimers that celebrity voices are impersonated when there is additional context which makes it likely that the voice would be considered something other than a mere soundalike, like direct reference to a work in which the impersonated celebrity was involved as part of the same publicity campaign.
And liability for commercial voice appropriation, even by impersonation, is established law in some jurisdictions, including California.
Where are the signs or symbols tying Scarlett to the openAI voice? I don't think a single word, contextless message on a separate platform that 99% of openAI users will not see is significant enough to form that connection in users heads.
The replies to Altman's message showed readers did connect it to the film. And people noticed the voice sounded like Scarlett Johansson and connected it to the film when OpenAI introduced it in September.[1]
How do you believe Altman intended people to interpret his message?
