It’s no secret Call of Duty has toxic players. You can hear them trash talk just about anytime you turn on voice chat in the game. But Modulate teamed up with Activision to use AI voice moderation to address the problem, and the results were worth shouting about.

The companies noted that toxicity exposure was reduced 50% in voice chat in both Call of Duty: Modern Warfare II multiplayer and Call of Duty: Warzone in North America.
