I couldn't really describe it all in one word. If I had to pick a word for my normal voice:
Eccentric.
The way I normally talk, is like, lazy, and boring, and guhhh, and my voice just sort of jumps all over to place regarding tone and pitch depending on what effect I'm looking for. xD;
But the reason why I can't really word my voice into one is because I'm good at talking in all different sorts of er... ranges. I'm a high soprano in choir, but I'm sure I could do fine in alto, and stuff like that. And talking normally in those ranges probably wouldn't be too much of a chore either. It'd just sorta sound strange. < < Also it depends who I'm talking to. (My voice gets higher as I start to get nervous.)
But. I talk with a very distinct valley girl accent. < < It's not like, SUPER HEAVY "likelikelikelikelikelike" Valley girl, but it's enough to get the microphone game in Mario Party 7 (or was it 8?) confused. < < *has to say 'YES' and 'FIRE' like, a thousand time before it finally registers.*
