Does anyone else constantly repeat what other people are saying in their head as they're saying it?

I’ll try to make it make sense.

So, I noticed that every time someone is talking (or a song is playing, etc) I’ll repeat what that person is saying in my head at the same time as they’re saying it. For example, if my friend is saying “Today I did…”, I’ll say the same thing in my head simultaneously, which results in me hearing the friend’s voice and my own inner voice saying the same thing at the same time. It’s like I’m reading a book and say in my head what’s written, only that I’m not reading, I’m listening.

I can’t seem to stop doing it, and I do it unconsciously without noticing. It doesn’t bother me though. Or maybe I overanalysed my own brain and gaslighted myself that i’m doing it. I have no idea at this point, cause anyone that I ask says they don’t do it.

I’ve been wondering if it can be explained by OCD. Like, maybe I do it so I can focus on what the person is saying and not on my other thoughts (that i can’t control at all)?

So… Does anyone also do it?
