Yes! I agree, if you can talk fluently sometimes, then it's not about directly approaching articulation with physical exercises. [Here I explain this](https://drive.google.com/file/d/1WAdyTN__wCGuDqHa5ygUuTxZDjmN5A5L/view?usp=sharing): In my opinion, * our **compulsion** is: Inability to initiate timely motor execution of a planned word or phrase * our **primary core** is: Inability to move articulators, Inability to relax speech muscles and Inability to breathe (as you can see in attached PDF document) **Conclusion:** I agree with you. As you mentioned, some stutterers have little control of breathing whereof diaphragmatic breathing is a greater contribution. Other stutters (this regards me), have little control over initiating articulators like tongue and jaw. The common fluency-shaping techniques are for this specific primary core ineffecient. More effective are tools to tackle the triggers that lead to anticipating, justifying and choosing this compulsive subset-response. Most severe stutterers on the other hand, have little control over relaxing the speech muscles whereof mindfulness is effective inasmuch as relaxation exercises
