Outline of Final Research Achievements

In this study, speech data by foreign learners of Japanese were collected under three types of conditions (relaxed, temporally stressed and psychologically stressed) and their acoustic characteristics were analyzed. . Overall, the speakers showed better mora-timing rhythm when they were in a relaxed condition. The major differences between relaxed and stressed (tense) situations were seen in pitch characteristics and dis-fluency markers, such as fillers and pauses.
