Roger that and true indeed. No two people are exactly the same. And stuttering by its very nature is inconsistent. Stuttering is comprised of blocks, repetitions, and/or prolongations. When you say, President, Statistic, or Stutter what happens to you? (Note that all these words have a plosive sound at the beginning). The /t/ and /p/ momentarily stop the flow of air and this often results in a block or a prolongation of the /s/ as it’s trying to move to the plosive /t/ but can’t. For some the /b,k,g,d,ch,j/ sounds do the same thing. It’s likely the transition from the /s/ to the /t/ in stutter, statistic, stolen, stacking, Stanley, etc that gets rascally. Yes? If so curious what would happen if you just barely made the /p/ or /st/ sounds in those words—Like slowly, gently making super light articulation contact and movements of the lips and tongue so as to not completely stop the flow of air.
