* 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.
I also think the "sounded like" is less clear than you think. Is it similar, yes. But how similar I am not sure what the line is but for sure I didn't think it was Scarlett Johannson. By saying it is Scarlett Johannson and relating it to her our brains will make the association though. That is marketing.
