voice-input

Let the player talk to NPCs out loud. Covers an always-on open mic with voice activity detection against the room's noise floor, push-to-talk and typing as fallbacks, ignoring the NPC's own voice coming out of the speakers, dropping coughs, clicks and filler words, fast speech-to-text (fal's Nemotron ASR, ~0.4 s, audio sent inline), and routing what was heard to the right NPC. Use when building or debugging mic input for a game, when the open mic triggers on noise or misses speech, when NPCs answer things the player didn't say, or when "nobody answers".
