once we have gotten past the ethical quandaries and doing it the right way. It would be cool to just synthesize voices for npcs and PC from a list of "character types" and maybe add accents for the main PC. So all games can have voiced audio (could be cool if it can also work in a retroactive way, like play a classic CRPG but have fully voiced characters would be pretty neat), which can be a mixed bag in modern day since realistically there is a budget and voice acting can take a ton of money if done right. So it means we as gamer if we can mod in new quests, we can use such system to truly expand thee game. Like I love real VA performances so I can see this as a "stopgap" so you can get the main questline done and many of the "good" side quests done but you can use this AI trained voice for the more smaller tasks that may not get as much love or as I said use it for modding.
