"John tends to be a bit of a goofball, making bad jokes and using off-beat humour and subtle irony. He has a typical nerd nature in that he is very passive and follows commands more easily than the others, complying with commands not because of their logical sense but because he was told to. His optimism through stalwart skepticism causes his friends think of him as the leader while he prefers just being their friend."

I’m looking for a mid-high pitched voice, sounding generically “nerdy” or “geeky”, slightly nasally.
