students learn a foreign language, due to language transfer, foreign accented pronunciations are often found. In this study, we aim at developing methods of automatic analysis of foreign accented pronunciations and automatic assessment of them. Acoustic analysis of the pronunciations should follow the process of removing acoustic feature biases from observations, which are extra-linguistic and caused by differences in age, gender and physical figure of students. This process is realized in this study by using the structural representation of speech. In our previous study, the effectiveness of using this representation to cluster students and estimate the need of correction for vowels was shown. In the current study, the validity of the clustering result is verified by comparing it to a phonetician's clustering of the same students and a new method is proposed to estimate the need of correction. Experimental results show that the automatic clustering performs reasonably similarly to the manual clustering and the new method outperforms the previous method by 7.4 points.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"3681","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"3671","bibliographicIssueDates":{"bibliographicIssueDate":"2011-12-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"52"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":79571,"links":{}}
