I'm not sure when it happened or how but when ever I talk to male Khajiit they have the voice type of an Argonian. I've been trying to search about this on the internet, to see if anyone else has ran into this problem. I've come up short though, and so I've come here to see if someone can help me with this problem.

I've verified the integrity of the cashe, so I know that's not the cause as I've done it several times. Can someone please help me? I need to fix this as it's starting to get on my nerves just a bit.

Do you have any mods? While one or two NPCs could get a miss-applied voice, all of them usually points to a mod issue. If you just have one or two of them, then Unofficial Patches fix things like this.

I've got quite a few mods but none that would change an NPC's voice or dialogue, it's mainly just immersion and armor mods.

Never assume a mod is not changing something in the game it is not supposed to be changing. Vanilla, the game does not mix up too many voices, at least from what i have heard.

I will move this to the mods section so you can post your load order, but I would encourage you to get the Unofficial Patches if you have not done so already, and make sure your Bashed Patch and Load Order is correct.
