The question posed by OP refers to the following research studies on stuttering recovery: Research: "*Bloodstein (1995) has suggested that the basis for true recovery would be if “stutterers could forget that they were stutterers" (page 450)* [Research](https://www.reddit.com/r/Stutter/comments/161bj9m/tips_to_improve_stuttering_from_the_research/): "*Unassisted recovery from stuttering: Self-perceptions of current speech behavior, attitudes, and feelings" "Researchers investigated recovered PWS, and categorized them between Group A: fully recovered speakers (with No Tendency to Stutter:* ***NTS participants****), who had different self-perceptions of their current speech behavior and their related attitudes and feelings when compared to Group B: recovered speakers, who said that they still have residual stutter remnants on occasion (who still have a Tendency to Stutter:* ***TS participants****)."* * NTS participants: Fully recovered individuals who don't have residual stuttering anymore. They no longer thought of themselves as stutterers. The reported absence of cognitive effort supports the likelihood that their speech production was normal because this is a characteristic that is assumed to be essential for normal fluency * TS participants: 99.9% recovered individuals show very little residual stuttering remnants, usually this only applies under certain conditions, like "*it's like about once a year \[when\] I get mentally tired*" (page 16). They did become more aware or concerned under certain circumstances, and sensitive to mental states or feelings that might prompt stuttering, and might think of implementing strategies for dealing with or repairing any possible stuttering. * All participants obviously had not literally forgotten that they used to stutter, but they certainly seemed to be moving in that direction. The present study suggests that complete recovery is possible. Self-guided change may be the primary reason for most of these recoveries; therefore, the range of recovery identified in this study may be related to the limits of different people’s abilities to self-manage their own change (page 21) [Research](https://www.reddit.com/r/Stutter/comments/160i3yk/tips_to_improve_stuttering_from_the_research/): "*Recovery from stuttering: The contributions of the qualitative research approach*" [Research](https://www.reddit.com/r/Stutter/comments/15zsh9m/tips_to_improve_stuttering_from_the_research/): "*Neural change, stuttering treatment, and recovery from stuttering*" [Research](https://www.reddit.com/r/Stutter/comments/15cl7wd/tips_to_improve_stuttering_from_the_research/): "*Why Stuttering Occurs: The Role of Cognitive Conflict and Control*" [Research](https://pure.eur.nl/files/48243924/Repub_117942_O-A.pdf): "*Spontaneous late recovery from stuttering*" * *"Causal attributions to recovery:* * *I no longer accepted that I was one who stuttered* * *I decided to treat my stuttering my own way* * *I decided to change something about my stuttering* * *The assumption that the recovery occurs out of the blue or is due to maturational processes may not be warranted because persons who recovered "spontaneously" frequently report self-management strategies to get rid of disfluencies."

Seery, has a whole chapter on people who outgrow or recover from stuttering" "Naturally fluent speech is produced by speakers who feel, think, and behave like normally speaking individuals when they talk. In essence, the aim here is a complete cure. This can be a realistic goal for preschool children. As discussed at length in Chapter 3, most of them experience natural recovery.* (page 253) (see [screenshot](https://drive.google.com/file/d/19aLwvcR1M2wVvTuVyDV_AYyDVqypOlcq/view?usp=sharing)) [Research](https://www.researchgate.net/publication/47795582_Empathy_Perhaps_the_most_important_E_in_EBP): "*If we examine individuals who have recovered from stuttering, we would find that the nature of their success lies in how they have dealt with loss of control*" (Quesal) [Research](https://drive.google.com/drive/u/2/search?q=johnson%20stuttering): "*Spontaneous recovery from stuttering" "Recovered stutterers had less often included stuttering as part of their self-concept." "Spontaneously recovered stutterers attributed their improvement to a variety of factors, including some techniques, contrary to modern speech therapy."
