that uses a computer to estimate the utterance content using only visual information without using audio information. Despite more than 40 years of engineering analysis, it has not yet been put to practical use. Therefore, we planned the “machine lip-reading challenge” for the purpose of revitalizing the field of machine lip-reading research. When we held the 1st and 2nd machine lip-reading challenges in 2018 and 2019, we set the classification problem of 25 Japanese words as a task. Since high accuracy was achieved in the 2nd challenge, in 2022, the 3rd challenge, we held the problem of estimating the phoneme label sequence of Japanese sentences as a task. In this paper, we report on the overview of the competition, the database, the models of the baseline and the three participating teams, and the results.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"5","bibliographic_titles":[{"bibliographic_title":"研究報告コンピュータビジョンとイメージメディア（CVIM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2023-02-23","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"23","bibliographicVolumeNumber":"2023-CVIM-233"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":224589,"updated":"2025-01-19T13:05:28.811025+00:00","links":{},"created":"2025-01-19T01:24:09.802410+00:00"}
