A reliable and practical subtype system of stuttering should enhance all related scientific work concerned with this disorder. Although a fair number of classification systems have been offered, to date, none has received wide recognition or has been routinely applied in research or clinical spheres. Whereas progress has been made in understanding…

The paper reviews approaches for the investigation of speech quality in stuttering treatment including speech quality research in areas beyond stuttering, stuttering treatment speech quality research, pertinent findings from nontreatment stuttering research, and issues in recent speech quality management research with stutterers. (Author/DB)

This paper reviews the prominent concepts of the stuttering event and concerns about the reliability of stuttering event measurements, specifically interjudge agreement. Recent attempts to resolve the stuttering measurement problem are reviewed, and the implications of developing an improved measurement system are discussed. (Author/JDD)

The paper argues that listeners are unable to judge unit-by-unit occurrences of stuttering acceptably. Reasons for this state of affairs and its implications for therapy, theory, and research are analyzed. An alternative speech production definition with its implications is proposed, and a diagnostic method of validating authentic stuttering is…

This paper discusses the speech monitoring process that underlies overt self-repairing of speech errors; the covert repair hypothesis, dealing particularly with explaining the variety of disfluency types from a restricted set of repair principles; quantitative and qualitative characteristics of disfluency in people who stutter; and the covert…
