If I still had an audible stutter, you could. It's inaudible
  now; it happens within my mind in the phonological loop, long
  before (well, about 200ms-400ms before) speech production.

  There's no pause in conversation; I can keep up the pace.

  But I 'feel' it. It's always there. It's an internal gap that
  never closes when I speak in most social situations.

  But when I write, that gap is not there. So, I take to writing
  much better.

  I also don't have the gap when I am speaking to my iPhone doing
  voice-to-text work. It just "comes out". I also don't have it
  when I have the floor as it were and people are actively
  listening in a way where I don't feel social pressure.

  But, those times are sadly rare. There's usually _some_ sort of
  social pressure to stop and let the other person talk. It's fine
  and all; it's the timing of conversation in the culture I'm
  raised in. But... I'm not good with it. It gives me that 1/4 -
  1/2 second pause that nobody hears but I can feel internally.
