This is about as close to Gene's approval we can get, so I'm happy.
She was also involved with
Earth: Final Conflict and
Andromeda, wasn't she?
She was.
Its for this reason I am happy she is in the film. Your right she wont be here forever so its nice to see her doing her famous computer voice again while she still can!
Hey...
With voice sampling, I wouldn't be surprised if Paramount, CBS, or whoever has already got so much of her voice on file that even when she's gone, they'll be able to continue using it, even to say new lines the real Majel never actually said.
"You have a new face...dear."
If you didn't mind a certain disjointed effect, like the message you get from one of those automated systems telling you that the library book you requested from another branch has come in, then yeah, you could do that. It would sound even more obviously artificial than the speech coming from Stephen Hawking's voice synthesizer, but it depends on what you're looking for.
Most people listening to the cut-and-paste sentences which resulted from such a process would probably be put off by the irregular flow of inflections and intonation. Studio processing could smooth it out somewhat -- maybe make it into a sort of Max Headroom quirkiness -- but by that point, it would have been much less costly simply to have another actor come in and read new lines.
