Design and Evaluation of the Corpus of Everyday Japanese Conversation

no code implementations • LREC 2022 • Hanae Koiso, Haruka Amatani, Yasuharu Den, Yuriko Iseki, Yuichi Ishimoto, Wakako Kashino, Yoshiko Kawabata, Ken’ya Nishikawa, Yayoi Tanaka, Yasuyuki Usuda, Yuka Watanabe

We show that the CEJC includes a good balance of adult conversants in terms of gender and age, as well as a variety of conversations in terms of conversation forms, places, activities, and numbers of conversants.

The National Institute for Japanese Language and Linguistics, Japan (NINJAL, Japan), has developed several types of corpora.

A Conversation-Analytic Annotation of Turn-Taking Behavior in Japanese Multi-Party Conversation and its Preliminary Analysis

no code implementations • LREC 2020 • Mika Enomoto, Yasuharu Den, Yuichi Ishimoto

In this study, we propose a conversation-analytic annotation scheme for turn-taking behavior in multi-party conversations.

Extending Search System based on Interactive Visualization for Speech Corpora

no code implementations • LREC 2018 • Tomoko Ohsuga, Yuichi Ishimoto, Tomoko Kajiyama, Shunsuke Kozawa, Kiyotaka Uchimoto, Shuichi Itahashi

Towards Automatic Transformation between Different Transcription Conventions: Prediction of Intonation Markers from Linguistic and Acoustic Features

no code implementations • LREC 2014 • Yuichi Ishimoto, Tomoyuki Tsuchiya, Hanae Koiso, Yasuharu Den

Because of the tremendous effort required for recording and transcription, large-scale spoken language corpora have been hardly developed in Japanese, with a notable exception of the Corpus of Spontaneous Japanese (CSJ).
