It's common that people seek cures for stuttering but the reality is there's no cure for stuttering and that anyone claiming to have a cure for stuttering is a charlatan taking advantage of desperate people. Yes, there are tools and techniques that can increase fluency, however, these are often 'case by case' where they help some more than others, and these improvements are often short-lived with the stutter returning. The most widely beneficial technique is acceptance of one's stutter and boosting one's self-esteem and self-confidence, as a person who stutters, to successfully participate in all facets of society.
