u/AxP3 got it right! Thanks for the shoutout! And for reading my posts! We stutterers have a healthy external timing circuit but a compromised internal timing circuit. The issues with our relatively-weak internal timing contribute to dysfluency; that's why we're almost perfectly fluent when we align our *timing* to external stimuli, like singing, talking with a metronome, or even speaking in chorus with other people. I won't go into too much detail, but you can learn more about it in my other posts. Specifically, regularly speaking in time with a metronome can improve your fluency. If you go into my posts you can get a more-complete explanation on what's going on neurologically, and some information on how to improve your fluency. Best of luck!
