You'll need your own commandset, and use a modified command button instead of Colonel Burton's button, since the command buttons control the sound effect.

Since both buttons have the UnitSpecificSound attached to the button.

CommandButton Command_ColonelBurtonTimedDemoCharge
  Command                 = SPECIAL_POWER
  SpecialPower            = SpecialAbilityColonelBurtonTimedCharges
  Options                 = NEED_SPECIAL_POWER_SCIENCE OK_FOR_MULTI_SELECT NEED_TARGET_ENEMY_OBJECT NEED_TARGET_NEUTRAL_OBJECT
  TextLabel               = CONTROLBAR:TimedDemoCharge
  ButtonImage             = SSTimedDemo
  CursorName              = PlaceTimedCharge
  InvalidCursorName       = PlaceChargeInvalid
  ButtonBorderType        = ACTION ; Identifier for the User as to what kind of button this is
  DescriptLabel           = CONTROLBAR:ToolTipUSAFireBurtonTimedDemo
  UnitSpecificSound       = ColonelBurtonVoiceModeTimedCharge
End

CommandButton Command_ColonelBurtonRemoteDemoCharge
  Command                 = SPECIAL_POWER
  SpecialPower            = SpecialAbilityColonelBurtonRemoteCharges
  Options                 = NEED_SPECIAL_POWER_SCIENCE OK_FOR_MULTI_SELECT NEED_TARGET_ENEMY_OBJECT NEED_TARGET_NEUTRAL_OBJECT CONTEXTMODE_COMMAND
  TextLabel               = CONTROLBAR:RemoteDemoCharge
  ButtonImage             = SSRemoteDemo
  CursorName              = PlaceRemoteCharge
  InvalidCursorName       = PlaceChargeInvalid
  ButtonBorderType        = ACTION ; Identifier for the User as to what kind of button this is
  DescriptLabel           = CONTROLBAR:ToolTipUSABurtonPlaceRemoteCharge
  UnitSpecificSound       = ColonelBurtonVoiceModeRemoteCharge
End

just change the 'ColonelBurtonVoiceModeTimedCharge' to 'OfficerVoicePlantRemoteCharge' or whatever sound you want. Then in your commandset for the unit, make sure that the commandbutton's names are included.

Also make sure the new buttons have a unique name, or else Generals will complain.
