I agree with Redfern
. The transporter accident cries are bloodcurdling.
It's both the actress, who clearly did a magnificent job, and whatever filters they put the voice through.
Curiously, the transporter accident resonates with the theme of Ilia and everything else scanned by V'Ger being turned into lifeless shadows of their former selves. It's a missed opportunity that nothing in the film suggests that any such resonance is actually intentional.
