| Challenge: | Speech corpora are indispensable to speech research; data centers are set up to meet this demand . it is difficult for speech corpus users to compare and select suitable corporata from the large variety of languages . |
| Approach: | They propose a search system that allows users to search for speech corpora interactively and visually . they add specification attributes and items to a large-scale metadata database "SHACHI" |
| Outcome: | The proposed system can search speech corpora interactively and visually . it would be easier for users to select suitable corporata from the large number of languages available . |

| Challenge: | NINJAL has developed several types of corpora for linguistic research . for each corpus NINJAL provided an online search environment, ‘Chunagon’ . |
| Approach: | NINJAL has developed several types of corpora for linguistic research . for each corpus NINJAL provided an online search environment, ‘Chunagon’, which is a morphological-information-annotation-based concordance system made publicly available in 2011 . NINjal has now provided a system ‘Kotonoha’ based on the ‘Chunegon’ systems . |
| Outcome: | NINJAL has provided a skewer-search system ‘Kotonoha’ based on ‘Chunagon’ systems. |

| Challenge: | a new conversation-analytic annotation scheme is proposed for multi-party conversations . current systems do not take a turn like a human even in simple two-party conversation . |
| Approach: | They propose a conversation-analytic annotation scheme for turn-taking behavior in multi-party conversations . they analyze how syntactic and prosodic features of utterances vary across four selection types . |
| Outcome: | The proposed model is based on Japanese multi-party conversations. |

| Challenge: | a corpus of everyday conversations that includes video data is a new approach . a large corpus contains 200 hours of speech, 577 conversations, about 2.4 million words . |
| Approach: | They have constructed a corpus of everyday conversations that includes video data . they will publish the corpus in march 2022, and part of it in 2018 on trial basis . |
| Outcome: | The corpus of everyday Japanese conversation (CEJC) contains audio and video data . the study shows that the corpus includes a good balance of adult conversants . |
