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)

Seventeen patients with Asperger syndrome (AS) and a mean IQ of 97 were compared with a control group of 13 patients with normal intelligence or high-functioning autism. Results found that pedantic speech was common in the patients with AS and may help differentiate AS from high-functioning autism. (Author/CR)

A study into the reasons why certain dialects become standard. (CH)

This paper discusses the phenomenon of elective mutism as a learned response and presents some techniques whereby speech can be elicited from the electively mute child. (Author)

Recorded voice samples elicit stereotyped personality judgments, generally consistent among listeners, but very seldom valid. The manner of stereotyping was investigated through analysis of the relationship of nine vocal characteristics (breathy, thin, flat, nasal, tense, throaty, orotund, rate, pitch variety) to 40 personality characteristics…

A vocal register is a series or range of consecutive frequencies that can be produced with nearly identical voice quality. On the basis of research three fundamental registers can be defined and described: pulse, a low range of phonation; modal, a middle or "normal" range; and loft, a high range, described by some as falsetto. These…
