I've always found voice recording and listening to yourself talk is a REALLY important exercise to understand the elements of breath control and speed and rhythm for working on my own voice. It's interesting me to hear that you have more of a problem choking on your words when you are forced to this for another person to listen to. Maybe it's because of memories your middle school therapy? In retrospect I also rue the speech therapy I was put through it in 3rd grade. I have come to be convinced that the worst thing well-meaning parents can do to their children is accept that there is a label for that child's problems. Every child goes through stages, and if there's a label that fits the child, the child will grow into it, like a piece of Japanese artisan fruit that is grown within a mold. If the problem was dealt with casually and downplayed, there's a good chance the child could grow out of it. There's an exercise I was doing the other day that might work for you too. I often feel inclined, when I'm typing my ideas up, to open my mouth and mutter... because the ideas flow faster and more easily with my mouth going. This has definitely not helped my stuttering habit at all, and I know I need to work on evening out my inner thought voice... which can oftentimes be twisted like rubber. Two things I was doing on this walk in the woods the other day: 1. I was practicing placing the idea of wistfulness at the front of the sentence I wanted to speak silently in my mind, as if it were an engine on a train. 2. I was stopping whenever I felt that I couldn't get going with my inner thought voice... and I realized that was actually helping me to practice appropriate pauses in phrasing that is important for me to learn, because I often talk too fast and too quietly, and run my words together.
