The purpose of this study was to investigate differences in single-syllable word repetitions between preschool children who stutter and children who do not stutter. The participants of this study were 24 children aged 2.1 to 5.0 years who stutter and a control group matched in sex and age. Audio- and videotaped speech samples consisting of at least 1000 syllables were analysed regarding frequency, number of repetition units, and pause duration of single-syllable word repetitions. Results showed that frequency and number of iterations of single-syllable word repetitions differentiate the two groups, and that the group of children who stutter produced significantly shorter single-syllable word repetitions than the control group.
