I've noticed the same thing with Dragonball Z "KAI" that SABC2 played. The voice overs were just not... them. So it is possible that these Naruto dubs are different. Although, I only came across Naruto on SABC2 last weekend and watched brief snippets of it, so I cant really tell.
All I know is, Naruto's English voice over is done by a woman.
