In this study we examined phonological encoding skills in 9 children who stutter (CWS) and age and sex matched children who do not stutter (CNS). Participants were compared in phoneme monitoring during silent naming of bisyllabic words. The groups were also compared in an auditory monitoring task. Results revealed progressively slower monitoring of phoneme located within bisyllabic words in CWS. The CWS and CNS were comparable in auditory monitoring. Findings shed light on the role of phonological encoding processes in stuttering.
