This guide will teach you to to disable the constant (or annoying) voice lines spoken by the AI Model announcer in Halo Infinite.
Step 1: Go to the Halo Infinite folder
Launch the file explorer and go to the hard drive where you installed your Steam games. The pathway should look like this:
Steam\steamapps\common\Halo Infinite\Sound\win\English(US)

The last folder depends on the language pack that you are using.
Step 2: Find the AI Model that you want to mute
Want to mute the AI CIRC because her voice lines annoy you? Look for these files:
- sb_001_vo_ai_un_mpsuitaisphere.pck
- sb_001_vo_ai_un_mpsuitaisphere_frontend.pck
Step 3. Transfer the sound packs to a different folder
Make a new folder and copy the sound packs there. Do not delete them so you can move them back in case something goes wrong with your game files in the future.
Step 4. Launch the game and equip the “muted” AI Models
If you removed CIRC’s audio lines, you can confirm that this method worked by equipping CIRC in your AI loadout. Do this for every AI that you modified and you will no longer hear their lines whenever you get a kill, death, objective, etc.
What Happens Next?
You will no longer hear the AI call out whenever a power weapon or powerup spawns in the map. However, if you’ve been playing a lot of multiplayer then this is no longer a big issue.
Who knows, your map awareness might even improve because you don’t rely on the AI anymore. Just keep paying attention to the team chat whenever an ally Spartan calls out enemies and objectives.
