new RESEARCH: Limited compensation but preserved motor variability in vocal pitch control of adults who stutter (2025)

new RESEARCH: Limited compensation but preserved motor variability in vocal pitch control of adults who stutter (2025) Typical speakers replicate the previously observed positive link between baseline pitch variability and compensation to pitch shifts. People who stutter show similar baseline variability but reduced compensatory responses and no variability–compensation correlation, suggesting a reduced or altered use of auditory feedback in vocal pitch control for many AWS, with notable individual differences. **The main new insight:** the positive variability–compensation link holds in typical speakers (ANS) but not in AWS (adults who stutter). Because AWS and ANS showed similar variability but different compensation, the data suggest AWS may be impaired in integrating auditory feedback into ongoing vocal motor control, or **alternatively may have reduced sensitivity to auditory feedback as a consequence of long-term adaptation to stuttering**.
