Controlling your stutter through self-hypnosis

Controlling your stutter through self-hypnosis Today while I was searching for some techniques to control my stuttering, I came across this youtube channel by Lee lovett. This man is promoting self-hypnosis to be one of the ways to control stuttering. How valid is this ? Have any of you cured stuttering through self-hypnosis ? Btw this is the link to his channel... it contains many videos of his clients that have conquered their stuttering. https://www.youtube.com/channel/UCjm1E-aPw9fMu5QAwaXkNPw
