NEW 2025 research: "Towards a dynamical model of transitions between fluent and stuttered speech" This paper introduces a dynamical systems framework for understanding stuttering, conceptualizing it as a qualitative shift in speech articulation driven by a single control parameter. This framework offers new insights into the nature of stuttering and potential approaches to intervention. While some structural and functional brain differences have been observed between PWS and PWNS \[12\], these differences do not necessarily indicate a pathological speech motor control system. Instead, they could reflect compensatory adaptations or developmental variations that allow PWS to manage the demands of speech production. \[13\] argued that PWS occupy the lower end of a speech motor skill continuum rather than having a qualitative difference from PWNS. It is also important to keep in mind that stuttering is an intermittent phenomenon, as PWS are capable of producing perceptually fluent speech. Taken all together, these factors suggest that the speech motor control system of PWS is possibly intact but operates within an abnormal range of control parameters during stuttering episodes. **Identifying the critical parameter(s) responsible for triggering stuttering could open up new possibilities for treatment**.
