Perception of Speech Rhythm in Japanese: Counting speech
units by a tapping task

This study examines how native speakers of Japanese determine the number of beats in words in order to search for a possible rhythmic patterning in Japanese. For this purpose, a finger-tapping test was designed and conducted. Thirty native speakers of Japanese, categorized into three age groups, participated in a task for which they were asked to repeat a word and tap the beat simultaneously. The number of taps and variations in the location of tapped beats were analyzed in total and for each group. The results demonstrate some evidence of a general preference for a unit more than one mora: i.e., some researchers have called a syllabic unit (e.g., CVV or CVC). This tendency was particularly prominent in the younger generation, and the age differences were statistically significant. This phenomenon of preferring a larger unit than a mora puts into question the conventional notion of the mora alone as a timing unit and suggests an alternative rhythmic unit in Japanese. A comparison of two five-mora words with different positioning of non-standard moras further suggests low rhythmic value for non-standard moras as well as the expected value for standard moras. The positioning effects suggest similarities with other languages such as English.
