Yes that is exactly what i am doing, i even try to go into negative state when talking to people so that blocks come and when they come i keep my breath intact, i keep on phonating and articulating, and you know what words just come out of my mouth ... even though not as crisp but not bad either... this is what i observed as well, when i used to anticipate fear/block , i used to go into subconcious brain fog,i used to stop phonation, articulation and instead start to push the consonant that i was stuck on or glottal stop... later with my own observations which were later confirmed by Valsalva Hypothesis that i just need to provide signals for phonation and articulation instead of doing effort impulse...
