Matsumoto-Shimamori, Ito, Fukuda, and Fukuda (2011) proposed the hypothesis that the transition from the core vowel (i.e. syllable nucleus) in the first syllable of a word to the following segment significantly affects the occurrence of stuttering in Japanese. The purpose of this study was to investigate whether word accent (i.e. an abrupt pitch fall in Japanese) affects the production difficulty of the transition from the core vowel in the first syllable of a word to the following segment in Japanese. The participants were 25 Japanese children who stuttered, ranging in age from 6;4 to 12;5. A two- and three-syllable word naming task was used. The frequency of stuttering was not significantly different between the words with and without an abrupt pitch fall, and among those whose positions of an abrupt pitch fall were different. These results suggest that word accent does not have a significant effect on the difficulty of the transition from the core vowel in the first syllable of a word in Japanese.
松本-岛守、伊藤、福田和福田（2011年）提出了一个假说，即日语中单词第一个音节的核心元音（即音节核）到后续音段的过渡会显著影响口吃的发生。本研究的目的是调查单词重音（即日语中的一个突然的音高下降）是否会影响日语中从单词第一个音节的核心元音到后续音段过渡的发音难度。参与者为25名口吃的日本儿童，年龄在6岁4个月至12岁5个月之间。使用了一个双音节和三音节单词命名任务。有突然音高下降和没有突然音高下降的单词之间，以及突然音高下降位置不同的单词之间，口吃频率没有显著差异。这些结果表明，单词重音对日语中单词第一个音节的核心元音到后续音段过渡的难度没有显著影响。
