Use visualization and imagine speaking fluently. Imagine driving a huge tractor or yak and leveling every thing —mounds, houses whatever and speak in the same way. Practice intentional stuttering. Exaggerate stuttering when you do so. Aim to stutter as much as you can during that time. Have fun with it. Stuttering loses its power when you take it on through imagination and reckless speaking in spite of stuttering. Stuttering really becomes a problem when we try to avoid it. The more speaking you can do charging on fearlessly the better. At a minimum you will “stutter fluently,” so blocks or reps are very brief. But talking, talking, talking without self-judgement is the way. That means learning to reward yourself EVERY time you speak, fluent or not.
