>Speech therapy is useless and ineffective most of the time That's not true in general. ST is the only thing that has shown efficacy most of the time, but it requires a lot of effort to be effective. I think many people will tend to give up, because it's too much of a struggle. Also note that ST does not in general refer to those "one and done" courses/seminars sold in various places. Those are more commercial in nature, and efficacy tracking becomes fickle.
