The reason we got Hatsune Miku, a virtual singer who doesn't sound quite human, rather than a perfect Vocaloid-based recreation of a well-known actor's voice, was that no actor was willing to volunteer to have their career destroyed by the latter. Therefore, they fell back on sampling an actor's voice to produce a new, distinct character, not one that sounded just like the actor. For “machine learning”, though, it seems the big players aren't even going to pay artists for the work they use, let alone try to avoid hurting their livelihoods.
