The real “therapy” for stuttering is self love and self acceptance, not a speech technique. Sure those help, but the “cure” to stuttering cannot be given to you by therapy. It’s really hard to do and I’m currently try to get there now. The past 2 years of my life have been the hardest for my speech. I went to college and it’s been a really hard adjustment. However I’ve had 2 stints of incredible speaking while being in college which was when I met the nicest girl who made me so happy to be me, and after I had a summer internship and felt like the man. Good speech is heavily coordinated to feeling good about yourself, being happy to be you. Speech therapy techniques don’t work when your brain has the same response to a speaking situation as it does if you were getting mauled by a tiger. You need to address the internal root cause before you are capable of using speech techniques effectively. Studies show that when you are experiencing the fight or flight response your mind stops being logical, abandons all step by step clear thinking, and is in survival mode.
