So, I did HCRI two years ago. I have mixed feelings about the experience. I was stuttering a lot at the time, and I was not in a good place with my speech. Just feeling really self-conscious and low about the whole thing. It's intense, partially because it's the first time I consciously as an adult proactively did something for my speech (in the sense of flying on a plane down to Virginia, I would never have dreamed of doing that at an earlier age). It was kind of a recognition of this thing I had, and realizing I had to acknowledge it. So, from that sense it opened the flood gates for me -- I met people there who also stutter, we still text and call each other weekly. I have this serious support group that knows exactly how I feel now, it's awesome. Since then, I've become a lot more comfortable with my speech/stuttering. That being said, the course itself emphasizes physical, rote exercises. It's two weeks long, super draining -- you speak in a slowed-down voice for at least the first week. I do think it "teaches" you from that sense how to use your articulators to phrase certain sounds, muscle memory. After two years though, I kind of feel the effect fading, I just don't have the same intrinsic sense of fluency I had right afterwards. The first year I felt really fluent, but I also developed avoidance behaviorisms because I became hooked to the fluency -- it's almost like "chasing the dragon". Now, my fluency is maybe back to how it was before, maybe a little better. I stutter a fair bit now because I just started a new job, new environment, etc., but I think I can stutter more easily and have a way healthier attitude about everything. So, I don't know, I don't really believe fluency shaping courses are the cure, just my opinion. I hated how artificial my voice sounded afterwards; I remember my mom talking to me right afterwards and saying how she missed my inflection. Personally, I always liked my inflection, my cadence, the rate of speech, I just had some blocks and repetitions peppered in there, too. Just my two cents! Feel free to PM or reply to this for more information.
