>Iv read an article that explained some of the physiological process of what happens when we undergo a block when trying to speak. [This](https://docs.google.com/document/d/1EAdO8ZXLSwt4xYkJIkuZ6dk_TCI6WaoDsHwyhonquNE/edit?usp=sharing) post explains on page 3, that, if we tense our muscles as much as possible, the physical tension can never lead to a speech block. You can try it out yourself: (1) Firstly, right now tense your tongue as much as possible, (2) Secondly, pronounce the letter /T/ with that tension. Conclusion: See? You are able to say the letter /T/ without blocking, if you tense your speech muscles at maximum. This could lead to the conclusion that 'tension' doesn't lead to a speech block, rather stopping with moving your tongue (or other speech muscles) to the next sound leads to a speech block. In my opinion, it's therefore more effective to change our initial question '*How can we relax speech muscles to reduce tension?*' to '**What disrupts us from moving speech muscles**?' and '**What do I prioritize over moving speech muscles**?'
