I didn't see this covered, but I apologize if I've missed something.

I've always been annoyed at the voice telling 3PO "Who are you" sounding so unlike a strom trooper. I mean, I do understand that the intention behind it was probably to not ruin the reveal for the audience that the Empire was already on Bespin. But the voice just sounds a bit silly, all gruff and weird. Besides, I don't think a normal storm trooper voice would be immidiately recognizeble, especially since they haven't been heard since ANH, so I don't se any harm in adding that.

Or, if keeping the reveal at all costs is a high priority, the voice could be changed to a normal person's voice, implying that the line is spoken by an imperial officer. I'd be happy so long as anything is done to it.

This is being fixed. The original voice is being restored. To hear how it will sound in Ady's ESB:R, watch from 3:36 in this video:
