I can't read minds, so even when I think I'm doing pretty well it's possible...eh probable that I've been read. Still, I make an effort to raise my voice just a bit and to speak more softly.
You've been doing this for 30 years...relax and work on your pitch if it makes you feel better. No one else will care.
Also, it's probably better to pick a quiet place...I find it harder to control my voice when I have to speak loudly?
