Also, voices, I hate to correct whoever said this...ARE genetic. Seeing as vocal chords are created by our genes, and those truly are what affect our sound, in a way it IS genetic. On top of that, it can also be influenced by our upbringing. Accents aren't genetic lol.

GM, voices are genetic, but accents are not. Even though Boba had a Kiwi accent until Jango died, he would most likely lose it as he grew older and was exposed to different accents.Children are especially adaptive when it comes to languages and accents.

That said, I do think your attempt to alter Morrison's voice is interesting. But I prefer the original Wingreen voice.
