This isn't so hard to understand if you've ever meditated. It becomes clearer that the internal monologue is a process that just runs on its own almost endlessly, and the feeling that we control it is mostly just an illusion. You can test this for yourself by trying to find out what your next thought is going to be. You never know until you have it, which indicates that the process is spontaneous and involuntary. I have ADHD and possibly some mild form of OCD so for me a big portion of the mind chatter is just counterproductive noise, and the only (healthy) freedom is meditation. I envy people who have no internal monologue, although they probably get the same noise just in a more abstract way.
There must be a language/hearing center in the brain that's being activated for some people and not activated for others. When I'm consciously having an internal dialogue, sometimes my tongue is lightly flickering around in my mouth as if I'm actually talking!
