To me, the hidden crux of this whole issue is "can this system be as effective to deal with as a human who is good at their job?" If that condition is met or exceeded, none of this voice stuff will matter. People won't care if the system discloses it's nature, or sounds creepy, if their airline reservation change (or whatever) goes abnormally well. If that condition is not met, which IMO it won't be in the near future, then we're just adding attempted manipulation and potential for abuse on top of an already bad UX.
