Whatever repetition you do after “taking a breath” fails is not a “regular repetition” - it’s an escape repetition. It’s more like a secondary behavior - where regular repetitions are a regular part of everyone’s speech. Our goal should be to become comfortable with regular repetitions (brief, no fear, smoothly transition into next sound). Tim talks about how the breath you are likely to take during a block (panic state) is probably going to increase stress. Anyways, it’s normal to talk on exhales. Try taking a normal exhale instead of a restricted chest inhale.
