Did Eminem use AI to change his voice on TDOSS?

I remember people saying here on release that he can't do the early 2000s voice anymore so he must've used AI.

I never bought into that, it sounds too good... and hopefully he does his next album entirely in his old voice and flow because it makes songs so much better.

Was there ever any news on this?

EDIT: when I say AI, i'm not saying HE didn't rap the words, I just mean did they use some AI to change the pitch etc. I don't believe for 1 second Eminem would generate a verse entirely using AI.

Though it does seem like he did use AI, and therefore cannot do the old voices anymore. Shame.
