Great question! It’s probably because you aren’t practicing the thing that’s the problem. If you are blocking on the word, you are already having a problem with it, so the practicing isn’t causing the fear. Like most people who block, the root cause is fear of people hearing your repetitions. Thr way to address it is to practice speaking *with voluntary repetitions*. If this sounds like the last thing you want to do, that makes sense! However, it also means that eventually, if you choose to try this, your brain will quickly start to feel less fear, and eventually, blocks and associated unwanted behaviors will diminish.
