He will be sitting, watching TV and just say "Yeah", then a minute or two will pass and he will say that again and then something else that I can't hear. As I said, this all started in the past week and it continues. When I ask him what he said, he says "nothing". It has me concerned.
My 94-year old mom talks to herself a lot. When I come into her apartment and she doesn't hear me, she's carrying on a whole conversation with herself out loud. I think it's just what thoughts are running through her head. Since I talk to myself a bit too, I don't worry about it. I think most of us have thoughts running through our heads and some people as they age just let those thoughts come out of their mouths.
I wouldn't worry about it, unless he's openly conversing with people who aren't there, i.e. having hallucinations. It doesn't sound like your dad is doing that.
