Is this an OCD thing?

I've always wondered if this was an obsessive compulsive thing. I know I do have some OCD tendencies already, but:

When I read words on a PowerPoint slide, for example, I always count the number of words and number of lines on a slide. Also if I'm speaking or listening to someone talk, I like to count (not out loud of course) the number of words and also syllables that are said, and like compare the number of syllables to the number of words.

I also notice that I sometimes will quietly repeat part of what I just said under my breath right after I say it.
