 "page_title": "How to measure whether an NPC voice change really helped with NPC Talk",
 "summary": "Use the voice-likeness-eval skill to score a cloned voice against held-out real clips before claiming it improved.",
 "who": "A modder tuning cloned NPC voices who keeps hearing mixed opinions on whether a change sounds better.",
 "problem": "Judging voice quality by ear is unreliable, and a thin-sounding clone could come from the reference clip or the model.",
 "outcome": "Speaker similarity and word error numbers over enough runs, showing whether the change helped.",
 "steps": [
  "Install the skills, for example `npx skills add https://github.com/christos-antono/NPCTalk`",
  "Check the voice server with npctalk health",
  "Ask the voice-likeness-eval skill to measure the current voice against held-out real clips",
  "Make your change (new reference clip, settings or model) and measure again",
  "Keep the change only if similarity improves across enough runs"

 "agent_prompt": "Using christos-antono/NPCTalk's voice-likeness-eval skill, measure speaker similarity and word error for my NPC voice <name> before and after switching the reference clip, over enough runs to be confident, and tell me which to keep.",
