I hum right before I speak to people and I stick and I push my tongue to the back of my teeth

I also have dyslexia so I don't have a tiny speech impediment on some words because I can't enunciate them.

My Ex girlfriend always saw it called me out. I never saw it but I will do a little hum like dut.dodo. right before I speak with someone.

Like a stranger or random.
Only if I did the asking.

When I solicit the conversation.

When someone starts speaking with me I am a chatterbox.

Only when I start the conversation with a stranger random.

Also

I find my self pushing my tounge to the back of my teeth .

I can speak well and fast with my teeth shut.

Is this more motor function or more a ASD cork?

Maybe a way to deal with a certain aspect of a certain social anxiety?

Or Maybe Dyslexia?

Does anyone else have similar experience?

Or questions
