Yes. My voice is way too loud. I think I'm speaking normally, but people will say things like "you don't have to yell" and "why do you have to be so loud?" It's even worse when I start talking about my special interests, because my already loud voice will get gradually louder and louder until I really am yelling.
I wish I could speak a lot more quietly, especially since I like talking about things that are considered taboo by the vast majority of people.
