title: Characteristics of disfluency clusters in adults who stutter.
abstract: OBJECTIVE
  The purpose of this study was to examine characteristics of disfluency clusters in adults who stutter (AWS) and to compare these characteristics to those previously reported for children who stutter (CWS).
  
  
  METHODS
  The spontaneous speech of ten AWS was sampled and organized according to utterance length in syllables. The overall number and type of disfluency clusters occurring in each sample were determined.
  
  
  RESULTS
  Findings indicated that utterances containing disfluency clusters were significantly longer than fluent utterances, and the occurrence of disfluency clusters was correlated with overall percentage of disfluency.
  
  
  CONCLUSIONS
  The results obtained in the present study for AWS tend to parallel those found for CWS and serve to validate their occurrence as a feature of the disorder of stuttering.
