Nolan sounds swful. It's almost like he received no voice direction at all and just went out of his way to sound wet and weak , with no inflection, enthusiasm or emotion. This is a hyper intelligent AI we are talking about here. It should have attitude. A great voice. And some bass tone. Or make it a smokin hot female voice. Or put a selection out there to be chosen by the player. Come on Bungie, get it right. If I can change the voice on my cars sat nav today, why not the AI voice on my computer assistant a few hundred years into the future. Sell voice packs, and make ' em good!!
