I've only seen some Japanese DragonBall from youtube, but I do notice a difference between Ms. Nozawa's performance there vs. the special from this past year. The special was the first I had seen of DragonBall in Japanese, and I can say that even as a dubbie, by the end of it I was used to hear Goku voiced by a woman.
My first reaction was "Wow...that's different." But I quickly stopped caring once I got into the mode of actually watching the show, and I considered her voice normal by the end. My experience with the show thus far had only been Schemmel (well, and the guy from Ocean's dub I can't remember), and since he doesn't have a manly voice for Goku, it didn't seem that odd to me (I recall the Toonami intro for the Other World Tournament where Goku says, "Got you!" and lets out a hitch pitched nnaaaaa-AHHHHH-aahhhhh!).
I'm not sure what the big deal about the voice is, considering King Kai's voice in the Funimation version was....I don't even know.
PS - Been lurking here for a few months (I stumbled upon the Special here) and I can officially say, I hate all of you for reawakening my interest in DB/DBZ.

Now I want to go and buy every episode and volume of the manga (have some scattered pieces of the Viz Manga that my parents bought when I was younger), which will be a challenge while paying for college.
Not a problem.
