Purpose: Disfluencies can be classified as stuttering-like disfluencies (SLDs) or typical disfluencies (TDs). Dividing TDs further, stalls (fillers and repetitions) are thought to be prospective, occurring due to planning glitches, and revisions (word and phrase revisions, word fragments) are thought to be retrospective, occurring when a speaker…

Examines the potential usefulness of various procedures employed to measure the adaptation in frequency rate of fluency failure, adaptation in temporal rate of speech, and automated analysis of on-off speech patterns in differentiating stuttering from cluttering. (SCC)

Examined the speech patterns of three- to eight-year-old children. Results showed that the children most often used "ah" phenomena and unfilled pauses as do adults. "Ah" phenomena showed a significant increase with age, especially between five and six among the females. (SRT)

Since speech pathologists are interested in the role nonfluent behavior may play in the onset or development of stuttering, this study compared the linguistic behavior of 17 fluent four-year-old children to that of 17 nonfluent children similar in age, intelligence, sex, sibling status, race, socioeconomic status, and education. The aspects of…
