This study analyzed a conversational speech sample from 10 preschool children stuttering for a year or less and age- and sex-matched nonstuttering children. Analysis indicated no significant between-group differences for either the duration of acoustically measured sound/syllable repetitions and sound prolongations or the number of repeated units…

Cluster formation in speech disfluencies of 15 preschool stuttering children and 15 nonstuttering controls was studied and compared. Clustering was found to be a significant factor in disfluent speech for both normal and stuttering children, but proportions of clustered disfluencies and size of clusters were significantly greater in the…

Speech-related reaction time measures and fluency-related measures of 24 adult stutterers and a like number of nonstutterers were assessed to determine their diagnostic discriminative power. Findings suggested that both fluency failures and the duration of laryngeal adjustment time are useful diagnostic measures for discriminating stutterers from…

This study attempted to empirically demonstrate the validity of a twofold classification of speech disfluency in adult stutterers. Instrumentation and procedures permitting reliable identification and coding of 9 disfluency behaviors were developed and applied to monologues of 180 adult stutterers. Factor analyses supported the two-factor…

Occurrence of residual stutterings on adjacent words caused by blotting out words at random in a reading passage was studied. (KW)

Stutterers were found to have a significantly greater number of pauses 150 to 250 msec long than nonstutterers, indicating that even the fluent speech of stutterers differs from normal speech. (Author/KW)

Nineteen stutterers provided samples of speech and reading from which scores representing 46 visible-audible phenomena were correlated. (Author)

Tape recorded speech samples from 10 4-year-old boys in their preschool classroom and in a structured interview situation were compared for frequency and duration of disfluency. (KW)

Offers a brief overview of children's speech development, discussing positive attitudes toward stuttering and outlining strategies for appropriate interventions by teachers and other adults. A checklist of factors to consider in making a referral for stuttering is provided. (KS)

Selected visible and audible features of stuttered speech were studied to determine whether these phenomena suggested a basis for differentiating among stutterers. Forty-six visible and audible phenomena of stuttering were examined in 23 stutterers, using a frame-by-frame analysis of sound motion picture film. Significant inter-subject differences…
