* OpenAI wanted an AI voice that sounds like SJ
* SJ declined
* OpenAI got an AI voice that sounds like SJ anyway
I guess they want us to believe this happened without shenanigans, but it's bit hard to.
The headline of the article is a little funny, because records can't really show they weren't looking for an SJ sound-alike. They can just show that those records didn't mention it. The key decision-makers could simply have agreed to keep that fact close-to-the-vest -- they may have well understood that knocking off a high-profile actress was legally perilous.
Also, I think we can readily assume OpenAI understood that one of their potential voices sounded a lot like SJ. Since they were pursuing her they must have had a pretty good idea of what they were going after, especially considering the likely price tag. So even if an SJ voice wasn't the original goal, it clearly became an important goal to them. They surely listened to demos for many voice actors, auditioned a number of them, and may even have recorded many of them, but somehow they selected one for release who seemed to sound a lot like SJ.
For a case that doesn't involve AI at all, consider situations where a voice actor in a cartoon is replaced (sometimes while still alive) by someone who can perform a voice that sounds the same. Decisively not illegal. Most people don't even find it immoral, as long as the reason for getting rid of the original voice actor wasn't wrong on its own (e.g. Roiland).
Because there are contractual clauses. Do you think Hank Azaria owns the voice of 'Homer Simpson'? Or does Fox own that? It would be crazy to develop a show and then be held hostage to your voice actors for all future shows - what if they get hit by a car?
