 SYNC: In the galley, just as Scotty exits, Spock orders: "Valeris,  please inform Starfleet Command that our warp drive is inoperative."  Yet Spocks lip movements seem to indicate that the name "Valeris"  was dubbed over "Commander Uhura," which would make sense given that  the latter is the ships communications officer and she is standing  right there, but was likely changed to match the subsequent dialogue  and action: Valeris asks, "A lie?"; Spock replies, "An error"; then  Valeris walks away as Spock continues to speak with Uhura.
