Make game characters talk back in their own voices
A modder built agent skills that wire talking characters into games; the GTA V example has 19 characters answering live in cloned voices about a second later.
Done with Claude Code
What they did
A modder packaged step-by-step skills, a voice server and a command-line tool for coding agents. The agent studies the game, sets up a voice service, makes voices from recordings, and connects characters. It then tests everything in the real game and writes notes for next time.
How it went
The GTA V example lets the player talk to anyone nearby with a mic. The author measured voice likeness on one character, with the best setup scoring 0.707 against 0.612 for an ElevenLabs clone.
Worth knowing
You need several paid accounts and keys, and should only clone voices from recordings you have the rights to.
Try it yourself with Claude Code
Using the make-npcs-talk skill, make the characters in [game] answer when I talk to them, in their own voices. First check the game version and how mods run, then set up the voice server and test it outside the game. Use only voice recordings from [folder I have rights to]. Show me your plan and any costs before creating cloud accounts or spending money.
Swap the highlighted [parts] for your own details.
