Abstract

The aim of the present study is to investigate how the phonemic characteristics influence on the disfluencies of children and adults who stutter. The participants were 10 children(9 boys and 1 girl) and 10 male adults. After having the participants to read out the Paradise-Fluency Assessment(Sim, Shin & Lee, 2004) passages, each of the productions were divided into syllables and words, and then the frequencies and the ratios of their disfluenceis were analyzed according to the specified phonemic features. In terms of the frequency of the disfluency, the participants stuttered more in the words which start with consonant than vowel. But they showed more disfluencies in the words initiated with vowel than consonant when the ratio of each phoneme's presences were considered. There found different tendencies among the phonemic features related with their disfluencies occuring with ralatively high frequency or ratio. It was difficult to find out the exact relationships among the order of the sound acquisition, phonemic complexity, and the disfluencies. To study the exact influence of the phonemic features upon the disfluencies, it comes important to consider the frequency of the stuttering itself together with the ratio of the disfluencies in which the opportunity of the specific sound's presence was considered. To compare the results of the different studies which has similar purposes, it seems important to consider the tasks and the methodologies in depth.
