I don't know what the method was named. Sorry. Your description of the speech therapy you received sounds like what I received. ​ >I did the program and practiced it at home as well, but I found that I was only fluent in the SLP clinic. Outside of that, the method was not practical/did not work for me. What was the response from your SLP when you told them you weren't achieving fluency outside? I'd come back to my therapist, and we'd discuss my successes and failures during the week. We'd assess where my blocks occurred and why. ​ >How do you reduce the tension that develop during a speech block? Muscle tension? Stop. Exhale (if you have any breath left.) Take a breath and start fluently. Trying to fight through the block was self-defeating for me. ​ I did the same therapy program in my teens as I did in my 20s. I didn't achieve fluency in my teens. That was on me though. I wasn't putting in the effort. In my 20s, I was really working the program. I'd practice in the car on the way to work. Once I was encouraged / allowed to use my fluency outside, I'd be pretty diligent about using it at work. Eventually, the fluent speech became the norm. Muscle memory, as it were. In my experience, just because therapy didn't work before, doesn't mean that it won't work. Just that it hadn't worked until it finally did.
