Not an answer but I've been thinking of how that at some point in the future we'll be able to use text to speech and the tech being developed today, where we can synthesize the sound and cadence of a real person just based on a few recordings, to replace voice actors in video games.

If a console integrates the system into its OS then maybe that can help reduce file size and also allow indie devs to add a lot of voice to a game without having to record a ton.
