Effect of Bi-Mora Frequency on the Frequency of Stuttering in Japanese Children who Stutter

Abstract

The purpose of this study was to investigate whether bi-mora frequency affects the frequency of stuttering in Japanese children. The participants were 15 elementary school children aged from 7 to 11 who stuttered. Thirteen nonwords with high bi-mora frequency and 13 nonwords with low bi-mora frequency were used. The findings indicated that nonwords with high bi-mora frequencies exhibited significantly lower frequency of stuttering than those with low bi-mora frequencies. This result suggests that bi-mora frequency might affect the frequency of stuttering.
