I will start to say that I am far from an expert in stuttering, but I did stutter for 15+ years and have basically stopped stuttering. Here are my thoughts and what I did. No person can hear me stutter anymore. In those rare events I know I am about to block on a word I know how to counter that. Then I don't think about it for a long time. I went from living a bad life to living a very good life now. If you want to improve speech you need to practice HARD. You basically need to launch a full scale war again stuttering. Let's pretend you are Russia which attacks Ukraine. Russia attack by air, land and sea, and they attack multiple places at the same time. They use artillery a lot, they send infantry, tanks and launch rockets from their ships. You need to have the same mentality when attacking stuttering. Do this you need something concrete - you need a strategy and plan because this will be your 24/7 war. The better you perform at your battles, the shorter the war will be. So where to get a plan? I bought the stutter book from Lee Lovett and all I needed was there. The book was 10 bucks on Kindle. If you have Kindle unlimited I think you can get it for free. Lee did stutter for a lot years but found some ways to overcome it. He wrote a book about it, then coached PWS for 5 years or so now. All this experience he have added to the book which I benefited a lot from. First results came after 2 weeks. So if you are really into overcoming stuttering and want to live a 99% fluent life I would recommend you try this because you haven't anything to lose.
