Preface: The tool does not re-distribute any game assets, nor does it interact with them in any way. Game assets are used only during voice training as a reference, to guide the algorithm to drive itself to a point where it can create voices that sound similar enough to the examples. Think about it as an automated digital impersonator. Regardless, avoid using the tool in an offensive/explicit manner. Make it obvious where you can, in descriptions that the voice samples are generated, and are not from real human voice actors. Any issues you cause with this are on you.
