Yeah, you're describing something very similar to Dean Williams's therapy for children, the Normal Talking model. Basically learning that stuttering is a behavior we do. While the behavior of stuttering is not voluntary, per se, we can change it. We intuitively know this, and this is what Johnson calls the interfering ... said differently stuttering is what we do when we try to not stutter. I think the primary source of impairment comes from our reaction to stuttering. The actual physical aspect of stuttering is relatively minor. Our reaction to it is what drives us into self-imposed isolation. While I don't necessarily think that the source of stuttering is an "incorrect" way of producing sounds / words, you're definitely right that you speak fluently in some (most) instances. Most of the words we produce are fluent. Dean Williams would say that when we begin to feel ourselves "interfere" we should remember what fluent speech feels like and go back to how that feels. (That's not the best description of his model, but it's the gist). I like this -- using the anticipation of stuttering as a cue to produce speech with reduced muscle tension and slower rate has been helpful for me. I think the biggest thing that has been helpful for me is to stop negatively evaluating myself for stuttering. The behavior of stuttering is not bad, it does not reflect negatively on me as a person. It just is.
