There is no quick fix 'hack' for a stutter. A lot of people don't like hearing it, but they need to. The best way to gain fluency (gain fluency, not 'cure'--there is no cure) is to accept that a stutter is something you will always have, face your dread, practice avoidance reduction, and learn to stutter more efficiently. It's not something that can be done in a day or a week or even months. It's something you need to do every single day, just like any other exercise. Most quick 'fixes' are just destructive in the long-term.
