This is a character that changes a lot in the terms of talking, they're usually very loud and excited but only with certain people. As you can see there's different speeds he talks in depending on the situation. His voice becomes husky in the slow talking. 

His voice isn't a deep voice but also not a high one so kinda in between? I'd recommend using your own voice if it isn't too deep. 

He's a very kind guy who is also gay and dating another guy who will be in the videos.
