Twenty adult male nonstutterers became more fluent when pacing their speech with a metronome. The degree to which they became more fluent was within the range which has been reported for stutterers. This finding suggests that the effect of the metronome on stuttering is not primarily a result of distraction. (Author/KW)

Relationship of frequency with which vocalization must be initiated in a given speech segment and frequency of attendant disfluency was investigated by comparing stutterers' readings of passages composed intirely of voiced speech sounds or containing both voiceless and voiced sounds, the latter requiring more off-on phonatory adjustments.…

This study examined a validation procedure combining self-reports with independent verification to identify cases of recovery from stuttering without formal treatment. A Speech Behavior Checklist was administered to 42 individuals familiar with recovered subjects' past speech. Analysis of subjects' descriptions of their past stuttering was…

Twelve adult stutterers were instructed to self-rate the speech naturalness (how natural their speech sounds) and feel naturalness (the amount of attention they are paying to the way they are speaking) of their speech under a variety of conditions across repeated rating occasions. Results showed that subjects were relatively consistent and valid…

Pressure buildup patterns preceding the onset of phonation were studied in 573 fluent utterances of 10 stutterers and in 552 utterances of 7 controls. Stutterers evidenced deviant patterns of subglottal pressure buildup and abrupt voice onsets more often than did controls; occurrence of jitter and shimmer did not differ significantly. (Author/JDD)
