I found an another (and last) piece of the puzzle.
I played Worms Battle Islands for PSP and Wii, then I tried Worms 1 for IOS and I discover that Napolean and DitzySoldier are scrapped speechs (Beta speechs), thats why their quality was low. About quality, with a great trick on Audacity I cleared the 75% of Napolean and DitzySoldier's quality.
P.S.: First I will update the speechs that I uploaded before, then I will work on the next speechs (The betas will be uploaded together).
