@article{oai:nagoya.repo.nii.ac.jp:02001048, author = {布目, 孝子 and NUNOME, Takako}, journal = {名古屋大学人文学フォーラム, Humanities Forum, Nagoya University}, month = {Mar}, note = {Previous research has indicated that Japanese native speakers have difficulty perceiving and producing the Chinese retroflex consonant /ʂ/ because Chinese has three types of sibilants, namely /ɕ/, /s/, and /ʂ/, while Japanese has two: /ɕ/ and /s/. This paper studied the production of Chinese sibilant fricatives by Japanese native speakers learning Chinese using the perceptual judgment of Chinese native speakers (Chinese speakers) and acoustic analysis. Speech samples of 30 Chinese speakers and 8 Japanese learners of Chinese producing 13 consonant–vowel syllables comprising one of three fricatives—/ɕ/, /s/, or /ʂ/—with the following vowels were recorded. The results of the perceptual judgment demonstrated that the production of /ɕ/ and /s/ was significantly more correct than that of /ʂ/. Moreover, the /ʂ/ produced by the Japanese learners tended to be perceived as /ɕ/ by the Chinese speakers. The acoustic analysis measures were of the center of gravity (COG) and second formant frequency (F2) at vowel onset. The results of Chinese speakers and learners were transcribed as scatter plot to demonstrate the two-dimensional acoustic space of a sibilant fricative. Japanese learners made clear, similar distinction between /s/ and /ɕ/. Most of the female learners’/ʂ/ overlapped with Chinese speakers’ /ɕ/ and learners’ /ɕ/. Conversely, male learners’ /ʂ/ was located on the boundary of male speakers’ /ɕ/ and /ʂ/. Compared with the results of the perceptual judgment of sibilant distribution in an acoustic space, female learners’ error /ʂ/ tokens overlapped with those of the learners’ /ɕ/. This finding may have been caused by the negative influence of L1 phonological category. Thus, the results indicated no clear differences between the correct /ʂ/ tokens and error/ʂ/ tokens uttered by male learners in the scatter plot of COG and onset F2. For further analysis, all the male learners’ F1 and F2 frequency at the vowel midpoint of each token were measured, and a scatter plot was transcribed as two-dimensional vowel space. Most of the correct /ʂ/ tokens were located in the same area with Chinese native male speakers in the vowel space, implying that the production accuracy of the following vowel in the sibilant vowel syllable plays an important role in the perceptual identification of Chinese sibilant vowel syllables. The error that Japanese native speakers produce as / ʂ / as / ɕ / may be because not only the consonant part but also the following vowels cannot be pronounced correctly.}, pages = {361--375}, title = {日本語母語話者による中国語歯擦音産出の特徴}, volume = {4}, year = {2021} }
