The recurrence ratio

The rationale for and method of computing a measure of stuttering recurrence that is superior to methods previously developed is presented. This measure, the recurrence ratio, contrasts especially with the traditional measure of “consistency,” the percentage measure, which yields misleading values.     

Pause loci in stuttered and normal speech

The mainstream of research comparing types of disfluency in stuttered and normal speech has typically omitted consideration of pause. In contrast, psycholinguisticresearch addressed to disfluency in normal speech alone has revealed the salience of pause in the study of fluency/disfluency. The research reported here, which focused on the antecedents and sequelae of filled pauses, revealed substantial differences in pattern of pause occurrence between stuttered and normal speech samples obtained from 20 matched subjects. The results are discussed in reference to relevant findings from the research on pause in normal speech.     

Early position and stuttering occurrence

Early sentence position is one of several features of verbal expression frequently reported to be associated with stuttering occurrence. Some studies also have reported the concurrence of these features with normal disfluencies. A review of the pertinent literature reveals that, among these features, early position is associated significantly more often with stuttering than with normal dysfluencies. Results of a study investigating stress patterns in the fluent utterances of stuttering and normal speakers yielded contrasts which speak pointedly to the relationship between early position and stuttering occurrence.     

Fluency,disfluency, dysfluency,and stuttering

The appropriate use of words, particularly certain words, is a persisting problem in the field of stuttering. This paper discusses some of the misuse involving four words basic to the field.     

Sound and pattern in artificial fluency: Spectrographic evidence

This study was designed to yield objective information relative to Wingate's hypothesis that common influences are operative in conditions widely reported to induce fluency in stutterers (Journal of Speech and Hearing Research, 1969, 12, 677; 1970, 13, 861; Stuttering: Theory and Treatment, New York: Irvington-Wiley, 1976). Spectrographic tracings of the same phrase uttered under four ameliorative conditions and, as usually spoken, were obtained from four stutterers and four normal speakers. Comparisons among these tracings support the inference that the reduction in stuttering typically found in these conditions reflects certain changes in manner of speaking, principally in the pattern of intonation.     

Stutter events and linguistic stress

In the research reporting the concurrence between stuttering and linguistic stress the identification of stress loci has been established regularly through intuitive judgment of the experimenter. The present study reports on a more objective determination of stress loci, and their concurrence with stutter events, which strengthens justification of the usual procedure for identifying stress loci.
