I created a High Elf NPC and I want to use him as a follower. So I want to use an elf voice type, but I don't get the option for him to follow my player. But when I put his voice type to "MaleEvenToned" it works perfectly fine. Is there way so my High Elf can have a High Elf voice type? Or no? Cause it's very dissapointing. And really annoying.

Unfortunately only certain voice types have dialogue that works for the follower quest that makes NPCs become followers. You can add unvoiced dialogue to some of the other voicetypes, but this is pretty complicated. Or, you can create a new voicetype follower - but that is even more complicated.
