Is there a software that can clone/recreate someones voice? if so what would you recommend for most accurate

Hello, im looking for advice is there a program that i guess sort of like machine learning to recreate someones voice, preferably something opensource or usable offline to protect privacy.
if there is something like that do you happen to know how much input it might need to get a fairly good result, just from not having alot of reference material.

thanks in advance :)
