There are ways to make Neo "speak" without destroying her mute image. The first few that come to mind are:

-Create auditive ilusions and speak through them.

-Use some sort of text-to-speech device.

PS (@Gundam): Casey's voice definitely fits Neo. If she can't sound like a psycho, even better; makes her a more believable psycho.
