When Cortana was first created, she (the AI) was about to pick out what herself would look like. Cortana designed herself, and so i believe she picked her voice as well.
Cortana did come from Halsey, but I doubt it was like any form of basic human-human cloning. Wasn't halsey's brain chunk just scanned and it's physiology pretty much copied onto a computer? There's no DNA being created as a result of this type of cloning.
Either way, even if they were the same, Jen Taylor wouldn't make their voices the same. Two distinct characters, and Halsey is a bit older and brittle at this time.
