If there is indeed a version to be released with new footage (remember it is Wikipedia) I wonder why they should put two more Ducky voices in (making three altogether in one movie). The eight minutes that were cut from the movie already had the sound recorded and I don't see why they would change the sound of finished scenes (the much the more scenes voiced by poor Judith Barsi

).
If there will be footage with new voices it may perhaps contain scenes which are completely new (scenes which may have been planned but never made in 1987/88).
I don't say that there won't be such a new released version, but I shall remain very skeptical until we get information from a more reliable source. Don't you think Aria would have told us if she had ever been asked to speak in scenes to be added to the first movie?
