The entire game hinges on the premise of being able to narrate and understand dynamic text on demand. Pre-recorded messages don’t work for this.

I think t's possible to use static voice, but it would create a very rigid experience, you would have to have a ton of generic sounds prepared and identify when to play each one. The fun of this is the fluid conversation. I can imagine the static responses being pretty terrible for unrecognized questions. LLMs provide really good RP.

"Tell me where the knife was hidden?"

"I don't understand your question"
