I have the same problem, only I find it hard to talk at a lower volume. The reason is because in my head, the pitch of my voice sounds normal. Yet, to others... it sounds loud. I've actually had a teacher get mad at me for it. I told her about this, and she called me a liar instead. >____> I think it's a normal thing for people on the spectrum (I'm not an aspie).
