I propose we suggest Jim James from My Morning Jacket, whose voice could tell me I'm about to be vivisected and as long as he sings it and lets out one of those gorgeous notes from nearly everyone of his songs.
Also: Warner Herzog. If you need a reason why (and simultaneously /thread, here's why, Warning: Language)
If this voice told you it was going to rip you limb from limb, you would bow to the voice. Oh, you meant if it had an AI too? Oh yeah, it'll definitely rip your limbs off and seem awesome.
