Paper short abstract:

Discuss the approach to apply Oral discourse database to preservation and succession activities of endangered language. As an example of documentation and visualization of performance of picture-story show by speakers of Hachijoan, I focus on the style of "storytelling" and discuss it.

Paper long abstract:

In this paper, we discuss the use of audio conversation materials in efforts to preserve and pass on a language in danger of extinction through the documenting and video recording of picture-story shows as recounted by Hachijoan speakers.

　The Hachijoan was designated as a "language in danger of extinction" by UNESCO in 2009. Even now, only a few people remain who can speak the traditional Hachijoan, and the natural conversation recordings collected to preserve the language are not sufficient to maintain the former system of the language. For this reason, after consulting and examining natural conversation transcripts with native speakers, we created revised texts. In rerecording the revised texts, in order to eliminate unnaturalness as much as possible, folktales were chosen as the subject material and the style of "storytelling" was adopted; thus, we were able to preserve both traditional Hachijoan texts and the voices on which these texts were based. In addition, to facilitate application in an effort to pass down dialects, we created picture-story shows, preparing texts for five regions.

There is a card game called "Hachijoan Karuta" by the Board of Education in Hachijo.The story of a picture-story show is superior in that it can listen and learn Hachijoan language speech of a longer unit, than "Hachijoan Karuta".

In addition to opening a video on which the talker played a picture-story show on the Internet, I made a file PPT-made picture-story show, and made it available for downloading and use.Not only to see and learn video, but also learners themselves can perform picture-story show in Hachijoan languages by downloading a PPT file.

The text of the picture-story show is in accordance with the actual situation of use, with linguistically backing.For that reason, learner himself can speak and perform in traditional Hachijo language.By a new performer talking about, the language is inherited although it is partial.By making use of picture-story show like this, we can contribute to the succession of Hachijoan.
