I think and speak very fast - but when I speak in front of others, my physical speaking ability doesnt keep up with my thinking and I end up saying UM a lot.
I watched others speak and never say UM and I just don't know how they do it.
Just like anything else, public speaking is a skill. To do it well requires focused practice. Learn to keep your mind and your mouth at the same pace and be willing to have silence while you think, rather than um, or have something more substantial to come out of your mouth than um.
It isn't easy of course, but any skill worth learning isn't.
When trying to improve public speaking skills this is a common thing to work on. It's certainly not easy at the start, but it is something that can improve a lot with practice, even for particularly nervous or fast-speaking individuals.
