White matter correlates of sensorimotor synchronization in persistent developmental stuttering.

Introduction: Individuals with persistent developmental stuttering display deficits in aligning motor actions to external cues (i.e., sensorimotor synchronization).

Speech rate association with cerebellar white-matter diffusivity in adults with persistent developmental stuttering.

Speech rate is a basic characteristic of language production, which affects the speaker's intelligibility and communication efficiency. Various speech disorders, including persistent developmental stuttering, present altered speech rate. Specifically, adults who stutter (AWS) typically exhibit a slower speech rate compared to fluent speakers.
