I have yet to hear a very convincing ai voice. I have tried them all. The problem is that subtle inflections and periodic excitement or apathy are always missing. There is no expression, just words. Without a talent team of people who are aquainted with their mannerisms carefully crafting it, I cant see it working. Whatever the case, it seems like using someones likeness to say things after death is tasteless and literally puts words in the mouths of people who cannot defend themselves. It will happen, but Id like to see it attributed to the maker, not the dead talking head.
