Purpose: This study examined the effect of speech rate on phonated intervals (PIs), in order to test whether a reduction in the frequency of short PIs is an important part of the fluency-inducing mechanism of chorus reading. The influence of speech rate on stuttering frequency, speaker-judged speech effort, and listener-judged naturalness was also…

Knowledge of variables that predict treatment time is of benefit in deciding when to start treatment for early stuttering. To date, the only variable clearly related to treatment time with the Lidcombe Program is pre-treatment stuttering frequency. Previous studies have shown that children whose stuttering is more severe take longer to complete…

This study, involving 24 preschool children with stuttering problems, found no significant differences between subgroups based on stuttering severity and phonologic ability. Phonologic difficulties of the disfluent word, and the fluent word following it, did not contribute to fluency breakdown regardless of the children's stuttering severity or…

A survey of 1,184 speech language pathologists found that of 2,628 children (grades 1-12) who stuttered, 62.6% had other concurring speech disorders, language disorders, or non-speech-language disorders. Articulation disorders (33.5%) and phonology disorders (12.7%) were the most frequently reported. Males were more likely to exhibit co-occurring…
