SLPs are generally successful at treating the issues they are actually trained to treat. Unfortunately, many have very limited training in treating stuttering and address it as if it’s articulation disorder. (If you can sometimes articulate the sound, it’s probably not articulation problem.) SLP with professional/accredited/academic training in treating dysfluency suggest that impactful stuttering comes from a different “place” than articulation. Articulation disorder is a problem where your articulators don’t know *what* to do correctly. Stuttering (blocking) is a problem where your articulators know what to do, but just refuse to do it.
