Dub Together

The developers describe how their game uses AI generated content like this:

Some of the artwork in this game was made with AI image generators and edited by hand afterwards. This covers the two player characters, the logo, the menu icons and the curtain texture. The English interface texts were written with the help of a language model and reviewed afterwards. The German texts are written by hand. The bundled Pack Creator uses a speech recognition model to find the spoken parts of a video you supply yourself and turn them into the lines you read out. An AI noise filter for your microphone recordings and AI-based separation of speech and background audio work the same way. All of this runs locally on your own machine and never sends data to an external service. These models only process material you provide yourself, they do not invent content of their own, and the result stays inside your own lobby.

Required on Steam store pages since 2024. It covers content that ships in the game, on its store page or in its marketing — Valve does not require a disclosure for AI tools used during development, so this says nothing either way about how the game was made. Check it on Steam.
