is important to understand the complex shape and movement of speech organs in the oral cavity for speech therapy. However, most existing study materials are two-dimensional, affording only a limited representation of complex shape and movement of speech organs in the oral cavity. In recent years, MetaHuman Technology (Epic Games, Inc), a platform that can present a realistic human body in real-time by adjusting body parameters, was recently developed. In this study, we report our attempt to visualize the oral cavity using MetaHuman as part of articulation intervention. The target speech sounds were [ta], [te], and [to], which form the basis of speech therapy. First, video recordings were taken of ten Japanese-speaking adults without speech and hearing problems. Using the typical speakers as a guide, we applied the Control Rig and Sequencer features of the Unreal Engine (v.4.72, v5.2.1) to generate computer graphic animations of MetaHuman's mouth. In addition, we have created a user interface that allows observation from any viewpoint while freely selecting display formats such as “oral cavity only” and “tongue only”. The constructed system was evaluated by the four experts in terms of its ability to understand the shape and movement of speech organs in the oral cavity. All experts evaluated the system favorably in terms of “ability to observe tongue movement from various angles,” “clear representation of airflow,” and “usefulness in clinical practice with magnified image of the face and translucent oral cavity.” However, there are some tongue shapes that are important in articulation training but cannot be reproduced with existing parameters, such as bilateral bracing and central groove formation. We will continue refining high-quality visualization systems for speech therapy.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告ヒューマンコンピュータインタラクション（HCI）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-03-04","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"17","bibliographicVolumeNumber":"2024-HCI-207"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":232990,"created":"2025-01-19T01:34:10.423403+00:00"}
