I did McGuire over 20 years ago, just before Anne Blight had a disagreement with Dave McGuire and went off to form Starfish. The main focus is taking large breaths, like you do when exercising or singing, then speaking with the force of the breath. My stammer was really bad at the time - I could barely say a word without blocking. After 3 days drilling and practicing, including doing street contacts where you stop strangers in the street to ask directions to somewhere difficult to say, I could speak pretty damn well, albeit with an unnatural big breath. I stood on a crate in front of over 100 people in Hyde Park in London and spoke fluently - an incredible feat at the time. I was on a high. I spoke fluently for 3 months, attended more courses and drilled other newbies. Then reality came crashing down and I relapsed. My family and mentor supported me and I picked myself back up. I saw a massive amount of egoism in people on the course, as well as in myself - perhaps not surprising given the level of confidence suddenly bestowed upon people. People might say quite offensive things, as if no longer hindered by a part of themselves that would usually be reticent to speak. I suppose that's a part of the learning process of social interaction that can be stymied by speech difficulties, a lesson one needs to learn at some point. I would meet up with a friend who was also on the course to practice street contacts. I had difficulty saying 'k' sounds, so I'd ask people, "Can you tell me how to get to McDonald's?" (Another tricky word - all those consonants bunched together). But I hated McDonald's. I hated what they called food. I hated the company, I didn't want to go there, and I knew where it was anyway, so it felt so disingenuous to be asking for it. I was part of the course for a year. The constant focus on speech was exhausting, the disingenuous contacts were doing my head in, and I felt like I couldn't live my as all my attention was on one issue. The technique wasn't helping me any more, although it had taught me a lot and shown that confidence was possible. It was a massive relief to tell my mentor that I was leaving to find my own solution. It's a lot of money. If you can afford it and think it might help, I'd say give it a go. There wasn't much about dealing with the emotional aspects of stammering when I did the course, which is one of the main factors for me overcoming stammering, and allows me to be more genuine and authentic in my communication. If it seems like a lot of money, try this: take in a big breath through your chest and force words out of your mouth. If you can do that, then I've just saved you a couple of grand.
