>*Any book recommendations would be helpful* I read 100s of books. The most interesting and important books that helped me to improve stuttering are research stutter books, researchgate or similar research sites. If you are interested, [these](https://www.reddit.com/r/Stutter/search/?q=tips%20research&restrict_sr=1&sr_nsfw=) posts discuss some important takeaways from these PhD researchers. If you are interested, [these](https://www.reddit.com/r/Stutter/comments/110c37i/comment/j88bc14/?utm_source=share&utm_medium=web2x&context=3) online manuals may be effective to improve stuttering, to subtract (instead of add) control and break the stutter cycle. Note that these strategies all include an acceptance element (where you learn to not care about speech errors). I recommend to approach the stutter cycle from all angles, so tryout different strategies instead of only one. Adding control like adding speech techniques may lead to a habit of excessively paying attention to stuttering which could make it harder to outgrow stuttering in my opinion. I recommend therefore to apply strategies that subtract control instead, like '*don't identify yourself with stuttering*' or '*don't link self-esteem to speech performance*' or '*don't justify avoidance-behaviors whereby you avoid instructing/deciding to move speech muscles during a speech block*'.
