The thing that's helped me overcome my stutter is advice that's dressed up differently than "overcoming stuttering". Whenever I would research "overcoming stuttering" years ago (when I had a severe stutter) I found very little information. I've also had the belief that if you improve yourself as a person, your speech will improve as an indirect result. Have to be brief cause I have little time to type. I explain it all in this video I made a while back: https://www.youtube.com/watch?v=6zkZwcXMcys Hope this helps!
