Are we fearing the stormtroopers being redubbed?

For me, I am not upset by the changes being done in the OT, the new scenes being inserted in. It makes the movies be rewatchable another few times within a short amount of time, because im fascinated with the new stuff (Alien 3 and LOTR extended editions come to mind, because after seeing theatrical versions for so long, its hard to process the new additions and must be viewed again).

The problem I have are audio changes. Boba Fett's voice being changed in Empire was the absolute worst thing that occurred in 2004 changes. (except for the lightsaber issues. And the biggest one of them all being Luke having green saber on the Falcon in Star Wars. Its the least talked about saber error!).

My memory doesnt process images the same that it does for sound and voices.
