I was in therapy off and on through well my elementary and HS. It wasn’t until college that it helped. I learned the “ease into the sound” technique, and a muscle-relaxation method that I still use to this day (27 years later). Why did it finally click in college? A few reasons, looking back. One, I was at a VERY low point. College was supposed to be this amazing experience where you met life-long friends. I had none. After struggling mightily through a presentation, I was at the bottom emotionally. Only way to go, so I went to my university’s Speech and Hearing center (it offers both MS and PhD in SLP) and went all-in. Two, I was emotionally mature enough to accept that therapy, and the program was as much emotional therapy as speech therapy. As others have said, speech therapy isn’t a cure. It’s giving you tools, tools that, if you put in the work, you can learn to use to increase fluency.
