We have 2 weeks before the trailer for Trek XII is released.
We may know then if thy used Majel's voice for the computer in that film. If so did they make a library of her voice to use for all Trek because if they did that would be awesome continuity and a great connection always to Roddenberry.
Would a different female voice matter? It wouldn't be cheaper in the long run after the next 2 Trek series in 20 years. Once built a library database could be used for decades since it would be digital.
