speech recognition of the elderly is less accurate, especially in smart speaker speech recognition, due to aging-related factors such as vocal organ deterioration, increased pauses, and decreased speech rate, leading to differences in acoustic features. Challenges include difficulty in recording elderly speech and limited data availability. The aim of this study is to enhance the accuracy of elderly speech recognition. As a proposed method, we built two models: one integrating age estimation into the speech recognition model and another employing adversarial multitask learning with GAN framework. Comparing the accuracy of these models revealed improved recognition for both elderly and general adult speech, demonstrating the effectiveness of the multitasking approach.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告音声言語情報処理（SLP）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-02-22","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"2024-SLP-151"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:33:21.774645+00:00","updated":"2025-01-19T10:26:10.171943+00:00","id":232474}
