I strongly suggest to *stop* thinking about your articulators. If they can sometimes move correctly, then they are not the problem and focusing on them will *make them not move*. Deep breathing (while talking) is the same as above. Stop trying to do it while talking - fluent talkers never regularly deep breathe while talking because talking happens on *normal or slightly bigger exhales*. My suggestion, in the moment, is *only* these things - voluntary stutter, normal eye contact, exhale, begin slowly, enunciate. I have practice suggestions too, but none of it involves thinking about articulators. This false idea came about from SLP who received no training in dysfluency, yet were tasked w treating stutterers. So they inappropriately started treating it as if it were an articulation disorder. It’s as ridiculous as treating a cancerous mole as if it were non-malignant.
