Currently, adversarial example can only be used if the attacked speaker verification model is completely known. Therefore, the attack performance on unknown models is poor. In this research, We propose a method to generate adversarial example based on the difference of speaker embeddings between input speech and enrolled speaker’s speech. This method can generate adversarial example if only the speaker embedding extractor part of the attacked model is known. In previous research, if the speaker embedding extractor of the attacked model is known, attack with proposed method can be carried out with high success rate, regardless of structure of scoring architecture. In this paper, we investigate the attack performance of the proposed method on speaker verification models with different embedding extractors. As a result, the proposed method is difficult to attack models with different speaker embedding extractor.","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":"2024-12-05","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"44","bibliographicVolumeNumber":"2024-SLP-154"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"updated":"2025-01-19T07:35:13.883503+00:00","created":"2025-01-19T01:46:24.090597+00:00","id":241664}
