Satoshi-kun (or Ash in the english dub) is voiced sejak a female in both english and Japanese however English had to VA's Veronica Taylor (from Kanto to the Battle Frontier) and Sarah Natochenny (from Battle Frontier to Present) opposed to his Japanese voice seiyuu who has been Matsumoto Rica from the beginning to the current Black and White 2 series (well present to be exact)
Paku Romi (voice actor of Edward Elric) also voiced Noboru Maeda, AKA penyu from Rainbow: Nisha Rokubō no Shichinin. He's also a short character, too. ^^
