This is the sort of thing that the GPT-Live model would excel at when it launches. I'm not sure you'd need the ALE model at all if they launch Live in the API with acceptable pricing as it solves the latency issues with voice entirely. It's an impressive piece of engineering that hasn't been discussed much yet, I guess because it's only a ChatGPT feature and not accessible to developers. The model can dispatch tools asynchronously while speaking which would be ideal for a game.
What you'd want is maybe some kind of Live model with voice warping so it can be given different Skyrim themed 'Nordic' voices, and then custom tools to interact with the game engine.
