Analysis of F2 transitions in the speech of stutterers and nonstutterers

Lingual coarticulation was acoustically examined in the fluent speech of stutterers and nonstutterers. Coarticulation was evaluated by determining the slope of second formant (F2) transitions following consonant release. In general, stutterers were found to display larger slope coefficients in comparison to the nonstutterers. The large coefficients were interpreted to reflect greater or quicker dimensional changes in vocal-tract behavior compared to those of nonstutterers. Discussion focuses on the speech motor skills characterizing fluent speech production.
