Almost all impactful dysfluency is almost entirely about a type of specific social anxiety. My sister had an articulation disorder and couldn’t say her own name ever. Her name was like Shannon, but she always said “I’m Dannon”. I could say my name perfectly when talking to my dolls, but froze up when answering the phone. This is very very common. Are you interested in learning the free, hard work stuff I did to become very fluent?
