- they used Johannson's actual voice in training the text to speech model
or
- a court finds that they violated Johannson's likeness.
From hearing the demo videos, I don't think the voice sounded that similar to Johannson.
But hiring another actor to replicate someone you refused your offer is not illegal and is done all the time by hollywood.
Probably this could indeed make them "win" (or not lose rather) in a legal battle/courts.
But doing so will easily make them lose in the PR/public sense, as it's a shitty thing to do to another person, and hopefully not everyone is completely emotionless.
If an actor is saying no and you have a certain creative vision then what do you do?
Johansson doesn't own the idea of a "flirty female AI voice".
That's exactly what was done when Jeffrey Weissman replaced Crispin Glover in Back to the Future Part II.
> Rather than write George out of the film, Zemeckis used previously filmed footage of Glover from the first film as well as new footage of actor Jeffrey Weissman, who wore prosthetics including a false chin, nose, and cheekbones to resemble Glover. [...]
> Unhappy with this, Glover filed a lawsuit against the producers of the film on the grounds that they neither owned his likeness nor had permission to use it. As a result of the suit, there are now clauses in the Screen Actors Guild collective bargaining agreements stating that producers and actors are not allowed to use such methods to reproduce the likeness of other actors.[
> Glover's legal action, while resolved outside of the courts, has been considered as a key case in personality rights for actors with increasing use of improved special effects and digital techniques, in which actors may have agreed to appear in one part of a production but have their likenesses be used in another without their agreement.
