The line is very clear. They are using inputs from the motor cortex, so the difference is really the same as it is between actually enabling vocal musculature and thinking quietly. I think understanding the internal monologue enough to inspect it is still very very far, and maybe not even feasible using implants, as it seems to be a spacially diffuse neural task.

Iirc, these neurons are also activated with internal monolog

People often don't realize they silently mouth some of the things in their internal monolog.

I don't find my mouth moving, but I can often feel my vocal cords matching the pitch of my inner voice.

I find that I can't say the word "world" in my head without either moving my tongue or mentally enunciating very carefully. It "sounds" more like "would" otherwise.

Yeah, that's interesting, I can really feel that rl sound push itself into your mouth.

We've discovered just how adaptive the brain is when it comes to trying to engage with the outer world. For the most part, the brain will simply make whatever required pathways needed, to adapt to the new tool it's using.
