I say that because I give lots of people these ideas that are free, available to try whenever, and that objectively help many talk fluently. I'll later see them posting "I'm willing to try anything to become fluent!". When I ask if they tried these ideas, they have not. Not a dig on your at all. Just my own frustration. Anyways, these ideas come from professional SLP's who are trained in dysfluency, some who are PWS, but now talk with great fluency. You have to do some scary things ,but it get easier and it works if you really commit to it. Basically, the urge to hide your repetitions is actually what causes blocks. Wanting to hide them is from anxiety about thinking others judge you when you have repeititons/prolongations. Disclose (either directly or by doing brief, controlled, voluntary repetitions) Make normal eye contact Begin slowly and enunciate, maybe even use a slight sing-song voice. Increase these 3 things when you feel a block coming on. (The urge to speed up is due to wanting to hide it/get it over with, so slowing down and enunciating is a way to reverse that. Slowing down without these other tools will not be helpful.) You can practice by calling random stores and beginning with a voluntary stutter. Choose a sound you are normally fluent on, only do a couple repetitions, but do it with intention/slowly - "Hello, wh-wh-what time do you close?" Most ideas came from here - lots of free resources, suggest to start at beginning of his podcast https://www.stuttering-specialist.com/about-us
