NPCTalk is an agent framework - Make any NPC in any game talk back with Fish Audio: skills, a self-hosted voice server and tools for AI coding agents, with a full GTA V example.

OverviewLink to this section

Make any NPC in any game talk back, with Fish Audio voices. Skills, a self-hosted voice server and tools that let an AI coding agent wire it up: the player speaks, the NPC answers in character, in a cloned voice, about a second later, and acts on what was said.

Built first for GTA V: walk up to anyone in Los Santos and just talk. Lamar roasts your hoodie, a cop tells you to file a civil claim and flips you off, Michael defends his robe like it's a business suit. Every line is written live in character and spoken in that character's cloned voice by Fish Audio Drama 3 (or S2 Pro), self-hosted on a serverless GPU. Most of the code doesn't know it's in GTA, so the same pieces work in other games: the skills say what a game has to provide, and how to build the rest.

Pick your agent. Each gets the same skills (Agent Skills format), the fal MCP server and the 'npctalk' CLI.

Inside a clone, '.agents/skills' and '.claude/skills' are copies of 'skills/', and 'AGENTS.md' holds the instructions ('CLAUDE.md' and 'GEMINI.md' point to it).

The 'npctalk' CLI. Plugin installs and clones put it on PATH ('bin/'). Anywhere else: 'uv tool install git+https://github.com/christos-antono/NPCTalk'.

NPCTalk is open-source, written primarily in Python, with 221 GitHub stars under the MIT license. It was last updated on 2026-10-16.
