Voicemod doesn't use AI. It has been around since 2009, it is just traditional audio processing techniques. No neural networks or anything of the like anywhere, unless they have a voice replication service in addition to their normal filters.

Newer versions do have AI, so OP should be able to use voicemod but not the AI section to stay within the rules. General microphone processing of course would be allowed.
