The present study investigated whether the articulation ability and speech rate control of people who stutter (PWS) were different from people who do not stutter (PWNS). Twenty PWS and 20 PWNS performed oral reading and speech shadowing. Speech and articulation rates and, the number and duration of pauses were analyzed. PWS showed slower articulation rates with more pauses than PWNS during oral reading, but not during speech shadowing. This suggests that PWS control speech differently under the two conditions. Furthermore, PWS showed a significant negative correlation between articulation rate and number of pauses during oral reading.
