What technique is used in this video? > tl;dr https://www.youtube.com/watch?v=pFmu27GM9-k tell me the technique used in this video ___ I have been stuttering from my 6th year. From then i have had my ups and downs on my stuttering intension. It is usually a month with mild stutter than, a months with "can't say a single world" stutter. This months is one of the worst months ever. And i think it is time to try self-stuttering treatment again. I found this video, and i need specifics about the technique used in it. https://www.youtube.com/watch?v=pFmu27GM9-k From what i have done when i went to a speech therapy, at first they are inhaling air with their nose, and exhaling it with their mouth. After few times of this, they add a word (please explain the progress of how many words should i say the first day, second day...). Then they go out in the public trying to talk to a crowd. I plan on reading some books out loud using this technique, and then going in public making small talk with strangers. And maybe join the StutterHangout sometime (i was terrified of joining them in the past). I have searched online for some good self-treatment, but most of them were "pay me $15 and you will magically stop stuttering" or books that are 150+ pages long.
