https://www.reddit.com/r/singularity/comments/193c0ay/sagaftra_approves_ai_voice_acting_for_video_games/ So, while this is a bad thing overall for voice actors it can be a boon for game developers to create a dynamic response system and actually talking NPC's i would guess. We have seen examples of this in Skyrim mods recently where you (almost) have a conversation or at least get a commentary to actions you have done that makes sense. Would be interesting to see how this could be used in the future.
