Sure, but none of those still lets you say whatever you want, you’re still locked to a few alternatives that effectively shoehorn you into a character. In the future, with the aid of AI you could match what you personally say or type to an intent and then map that to pre-baked responses. With attacking you or running away as a response to aggression and a “haha very funny but back to the matter at hand” when you’re being silly. And it’s only when we’re there that I’d, personally, say a “silent” protagonist is as immersive as a voiced one.
