The purpose of this paper was to examine acoustical characteristics of phonatory offset-onset mechanism in the connected speech of female adults with stuttering and normal nonfluency. The phonatory offset-onset mechanism refers to the laryngeal articulatory gestures. Those gestures are required to mark word boundaries in phonetic contexts of the connected speech. This mechanism included 7 patterns based on the speech spectrogram. This study showed the acoustic features in the connected speech in the production of female adults with stuttering (n=1) and normal nonfluency (n=3). Speech tokens in V_V, V_H, and V_S contexts were selected for the analysis. Speech samples were recorded by Sound Forge, and the spectrographic analysis was conducted using Praat. Results revealed a stuttering (with a type of block) female exhibited more laryngealization gestures in the V_V context. Laryngealization gesture was more characterized by a complete glottal stop or glottal fry both in V_H and in V_S contexts. The results were discussed from theoretical and clinical perspectives.

The purpose of the present study was to investigate the characteristics of disfluency in 3~5 year-old multicultural family children(MFC). 24 children(12 MFC, 12 Korean monolingual children, KMC with the same chronological age and language age) participated in this study. The experimental tasks consisted of story retelling tasks(SRT) and picture description tasks(PDT). In all the tasks, the scores of total disfluency of the MFC were significantly higher than those of the KMC. In all the tasks, the frequency of abnormal disfluency of the MFC were significantly higher than those of the KMC and the speech rates of the MFC were significantly lower than those of the KMC. The disfluency observed in MFC indicates that language ability influences on their disfluencies and fluency support of MFC is an important factor in general language support.
