The second technique recommended by Self Therapy for Stutters from the Stuttering Foundation of America is "When you stutter, stutter easily, gently and smoothly without forcing".
The aim here is not to stop stuttering and speak fluently, but rather to continue stuttering in a smoother, gentler fashion. For example instead of having a hard block on a word, rather stutter through it.
Speaking is a complicated process, your voice box, jaw, mouth, tongue and lungs all need to work in unison at rapid pace. Tension in anyone part of this speaking mechanism can lead to stuttering. So by focusing on speaking in a more gentle, relaxed smooth manner can help with fluency.
Speak easily and smoothly, sliding into the sounds of words with light, loose movement of your tongue, lips and jaw
