Yes, the robotic filter is slightly missing for the AI part. Same problem I encountered for Zorri in Ascendant (but surprisingly not Kylo).
Maybe decreasing the volume slightly for that part could help disguise it better. Otherwise, we’d have to figure out how Lucasfilm designed the Vader voice filter.
To reiterate, I don’t think it’s that noticeable. Only people who are purposely paying attention would notice.
Ryan Golden has practically perfectly replicated the Vader filters, even for each individual movie (it was different each time). I could ask him about it. I’m friends with him.
