Does anyone have sporadic sounds?

when i go on tne streets, i sing in silence in my head. Sometimes i forget and sing out loud, really awkward. 

I also talk alone all the time. i try to mask it the best i can. If i have  someone to talk to, i stop but most of the times, there's no one around.

i can understand that people get afraid cause it is really awkard. But i just can't help it. I try to mask the best i can. 

I just had a thought, I often chew gum at work as I get sometimes have jaw tension, I'm wondering if that might help channel some of the speaking and singing energy to reduce accidentally speaking aloud? Perhaps not helpful but mentioned just in case!
