1) Developmental stuttering can never really disappear, it is a disorder of neurological and genetic origin (with the addition of environmental factors). But we can manage to reduce it or accept it (which will also reduce it in the process) 2) qto reduce blockages, I work on two methods with my speech therapist (there are other methods that other people may explain, but I don't know them: - Learning techniques, such as syllabified speaking (speaking syllable by syllable), erasm (saying weakly the sound on which you stutter and the rest of the word normally), pauses, breathing and slowing down, etc. - Acceptance of stuttering: basically wanting to hide and avoid stuttering reinforces stuttering. This involves forcing words, looking away, repeating entire sentences, tensing up and hitting, etc. for secondary fighting behaviors. For avoidance, this involves changing words, avoiding speaking in public or at all, etc. Forcing yourself to accept stuttering voluntarily without engaging in combative behaviors, to talk about stuttering to those around you or to those around you (without apologizing for your stuttering), allows you to change your outlook on your stuttering (and therefore your anxiety about it) , and accept what we call your neurological stuttering (the one that will always be there, but without the secondary behaviors that weigh it down) Here I hope I helped you. Don't hesitate to send me a DM or consult a speech therapist with whom you can work on these points.
