See this YouTube link: https://youtu.be/bNkOeIBKZNs It shows very serious stutterers who are using a breath technique to speak to strangers when 4 days earlier they could not even say their names! I overcame my stuttering by dealing with an abusive childhood through psychotherapy 5 years ago. I stuttered from age 4-5 until I was 70! That’s an awful long time to be searching for an answer. It’s never too late. Good luck, Sue
