Hello @TheEdgeOfDestiny!
So glad you like the skin! I am sorry the VO feels out of place, or like a piece of puzzle missing to make it whole. I do want to give a little bit of the "Behind the Scenes Work" on Little Devil Teemo VO. It might shed a little light on why we decided to not process the original VO.
I was super excited for this skin to come about and jumped on the idea of wanting to process the original Teemo voice so that the True Teemo that we had all been waiting for could come out to the rift and scare us all. One of the decisions we had made with this Teemo is that he stay cute, demon but cute! So with all my demonic research and inspiration, I tried my hand at making Teemo sound like a demon. This was 2 weeks of trying to get Teemo to sound just right...the results were disastrous and I will explain the reasons why.
There were two options to go with on Teemo's voice: pitched super low and scary, very large demonic-like and the other which was psychotic, not pitched. This non-pitched effort would be done via re-recording Teemo's original voice talent and getting the VO to feel psychotic. The pitched low option failed hard because it was the opposite of cute and got super annoying really quick. It was also technically hard to do this pitch on the original VO of Teemo since that VO is actually pitched up to a higher frequency, so when I added the low pitch processing, it sounded like a 14 year old boy and felt extremely out of context. The only way to do this was to re-record a male VO talent and have them hopefully hit those Teemo feels but at a lower frequency, so I could pitch it lower and have it feel demonic. So this was just a bad option and was just feeling bad with Teemo walking around the rift sounding like a 14 year old kid.
The second option of pitching up was also a hard decision because it meant re-recording Teemo's voice talent and adding an element of psychotic-ness to the voice...Again, using my own voice (which was embarrassing) and running around the rift felt really annoying and overall not cute, nor like a devil. Thus the idea I went with in the end was using the moment during the recall and death when Teemo's true face was revealed, where I could go as ham as I could and use that crazy low end demon voice. I did this by recording a Rioter in house and pitching it as you hear Teemo currently. This has then allowed for all of us who play Teemo to not get super annoyed, and to be much more surprised at the recall and death when that true form is shown.
Hopefully this helps clarify why we chose the non-processed version vs. the processed version. Please hit me back with any feedback. So far I heard some really cool options reading the comments in this thread.
