Stuttering is basically caused by the brain's inability to process the speaker's voice as s/he speaks. To minimize stuttering do not let the brain process the speaker's regular voice. Process another voice. Techniques: 1) Diaphragmatic breathing, Costal breaths 2) Speak louder or softer, speak slowly, whisper, sing, speak in a falsetto 3) Use a prosthetic All of the above have been very helpful to me.
