I think there's a pretty reasonable answer here in that the similarities to Her are quite obvious, and would be regardless of whose voice it was. If you wanted it to be SJ, reaching out right at the last minute seems rather odd, surely you'd reach out at the start?
There are three timelines that seem to be suggested here
* OAI want the voice to sound like SJ
* They don't ask her, they go and hire someone else specifically to sound like her
* They work on, train and release the voice
* OAI, too late to release a new voice as part of the demo, ask SJ if they can use her voice
This requires multiple people interviewed to be lying
Or
* OAI hire someone for a voice
* They train and release the voice
* People talking to a computer that reacts in this way is reminiscent of Her
* "We should get SJ as an actual voice, that would be huge" * Asks SJ
One third one, probably more middle of the road?
* OAI hire someone for a voice
* They train and release the voice
* People talking to a computer that reacts in this way is reminiscent of Her
* "Is this too similar to SJ? Should we ask them?"
* Asks SJ
> He compared Johansson’s case to one brought by the singer Bette Midler against the Ford Motor Co. in the 1980s. Ford asked Midler to use her voice in ads. After she declined, Ford hired an impersonator. A U.S. appellate court ruled in Midler’s favor, indicating her voice was protected against unauthorized use.
Sure, though worth noting that they hired a Bette Midler impersonator to sing a cover of a Better Midler song (edit - after asking and getting a "no")
To be honest, I'm not really that convinced it sounds like her
(I'm in a camp that Sky voice doesn't really like Johansson's)
