There is a substantial amount of literature reporting the incidence of phonological difficulties to be higher for children who stutter when compared to normally fluent children, suggesting a link between stuttering and phonology. In view of this, the purpose of the investigation was to determine whether, among children who stutter, there are…

The relation between stuttering and aspects of language, including phonology, has been investigated for many years. Whereas past literature reported that the incidence of phonological difficulties is higher for children who stutter when compared to normally fluent children, the suggestion of association between the two disorders also drew several…

Stuttering has been considered a heritable disorder since the 1930s. There have been different models of transmission that have been proposed most involving a polygenic component with or without a major locus. In spite of these models, the characteristics being transmitted are not known. This study used two different tasks--a tapping task that is…

A study investigated frequency change and duration of the second formant (F2) transition in speech samples recorded close to stuttering onset in 10 preschoolers who stutter, 10 who recovered from stuttering, and 10 controls. Near stuttering onset, children whose stuttering persisted demonstrated significantly smaller frequency change than the…

Conversational speech of five children who stutter was recorded and then portions manipulated to modify interval duration and vowel duration. Results indicated that both interval and vowel durations moderately affected listeners' perception of stuttering. Generally, repetitions with short vowel and interval durations were judged as more…

Preliminary findings from a longitudinal study of 32 preschool children who stutter and 32 nonstuttering controls reveal 4 subgroups: (1) persistent stuttering; (2) late recovery; (3) early recovery; and (4) control. Comparative data for the groups regarding frequency of disfluency, acoustic features, phonologic skills, language development,…

This study compared duration characteristics of single repetitions of single-syllable words in the speech of 15 preschool children near the onset of stuttering to those of 18 nonstuttering children. There appeared to be a tendency for repetitions of very early stutterers to be faster than repetitions of nonstuttering children. (Author/DB)
