Abstract

In this study, phonological similarities of two-kanji compound words used by both the Japanese and Vietnamese languages were objectively calculated by two indexes of phonological distance and phoneme similarity. The phonological distance of 1,475 (71,67%) of two-kanji compound words used in both languages (71,67%) was automatically calculated by R cba package (Buchta & Hahsler, 2016), and by the R phonosim package (Yu, 2016; Version 0.1) for phoneme similarity. The mean of phonological distance was 6.06 with a standard deviation of 2.52. This index indicates that the smaller the phonological distance, the higher the phonological similarity. On the other hand, the mean of phoneme similarity between two languages was 0.5 with a standard deviation of 0.2. Phoneme similarity was dispersed from 0 to 1, and the closer it was to 1, it showed that phonological similarity was higher. The correlation between phonological distance and phoneme similarity was very high (N=1,475, r=-0.92, p<.001): the two indicators were very similar. In the indexes of phonological similarities between the Japanese and Vietnamese languages can be found on the web search engine (http://kanjigodb.herokuapp.com/, for more information, see Yu, Tamaoka & Hoang, 2019). This search engine is expected to contribute to developing the learning/teaching curriculum and materials of two-kanji compound words for Vietnamese learners of Japanese.
